                                   TAX OPINION


Ladies and Gentlemen:

      You have requested our opinion as to certain federal income tax matters in
connection with (i) the merger (the "KSL Merger") of VLI Sub A LLC, a Delaware
limited liability company ("VLI Sub A"), with and into Kaneb Services LLC, a
Delaware limited liability company ("KSL"), pursuant to the Agreement and Plan
of Merger (the "KSL Merger Agreement") dated as of October 31, 2004, by and
among Valero L.P., a Delaware limited partnership ("VLI"), Riverwalk Logistics,
L.P., a Delaware limited partnership ("VLI GP"), Valero GP, LLC, a Delaware
limited liability company ("Parent GP"), VLI Sub A and KSL, and (ii) the merger
(the "KPP Merger" and together with the KSL Merger, the "Mergers") of VLI Sub B
LLC, a Delaware limited liability company ("VLI Sub B"), with and into Kaneb
Pipe Line Partners, L.P., a Delaware limited partnership ("KPP"), pursuant to
the Agreement and Plan of Merger (the "KPP Merger Agreement" and together with
the KSL Merger Agreement, the "Merger Agreements") dated as of October 31, 2004,
by and among VLI, VLI GP, Parent GP, VLI Sub B, KPP, and Kaneb Pipe Line Company
LLC, a Delaware limited liability company. All capitalized terms which are not
defined herein shall have the meanings assigned to them in the Merger
Agreements.

      In rendering our opinion, we have examined the registration statement on
Form S-4, as amended, filed by VLI with the Securities and Exchange Commission
on January 25, 2005, Registration No. 333-120726 (the "Registration Statement"),
including the joint proxy statement/prospectus included therein and the
documents incorporated by reference therein, and we have made such
investigations of law as we have deemed appropriate as a basis for the opinions
expressed below. As to any facts material to the opinion expressed herein which
were not independently established or verified, we have relied upon written
statements and representations of officers and other representatives of VLI, KSL
and KPP (the "Representations"). We have also assumed that the Mergers will
occur in the manner contemplated by the Registration Statement and in accordance
with the Merger Agreements with none of the terms or conditions of the Merger
Agreements being amended, waived or modified,

Valero L.P. July 1, 2005 Page 2 and there are no arrangements other than those set forth in the Merger Agreements between the parties thereto. In rendering our opinion, we have also assumed the due authorization, execution and delivery by each party thereto of all documents, the genuineness of all signatures, the authority of all persons signing such documents on behalf of each party thereto, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals and the conformity to the original document of any document submitted to us as a certified, conformed or photostatic copy. We have assumed that all representations made "to the best knowledge of" any person will be true, correct and complete as if made without that qualification. Subject to the limitations and qualifications set forth herein, we are of the opinion, based on existing provisions of the Internal Revenue Code of 1986, as amended (the "Code"), existing Treasury regulations, existing court decisions, and existing public rulings and other administrative interpretations, and based on our review of such documents as we have deemed necessary, the Representations and all representations and assumptions contained in the Merger Agreements or Registration Statement, all assumed to be accurate as of the Effective Times, that: (i) none of VLI, VLI Sub A, VLI Sub B, VLI GP, or Parent GP will recognize any income or gain as a result of the KSL Merger or the KPP Merger (other than any gain resulting from any decrease in partnership liabilities pursuant to section 752 of the Code), (ii) no gain or loss will be recognized by holders of VLI Common Units as a result of the KSL Merger or the KPP Merger (other than any gain resulting from any decrease in partnership liabilities pursuant to section 752 of the Code), and (iii) 90% of the combined gross income of each of VLI, KSL and KPP for (x) the calendar year ended December 31, 2004 and (y) the calendar quarter ended March 31, 2005 are from sources treated as "qualifying income" within the meaning of section 7704(d) of the Code. Our opinion is based, in part, upon relevant legal authority in effect as of the date hereof. We provide no assurance that the legal authority upon which this opinion is based will not be amended, revoked or modified (with or without retroactive effect) in a manner which would affect or change our conclusions. Furthermore, should any of the representations or assumptions set forth or referred to above prove to be inaccurate, as of the Effective Times, our opinion may change. Our opinion is limited to the federal income tax matters addressed herein, and no other opinions are rendered or can be inferred with respect to any other matter not specifically set forth in the foregoing opinion. Specifically, no opinions are expressed with respect to the tax consequences of the Mergers or the ownership of VLI Common Units under any foreign, state, or local tax law. Our opinion is rendered as of the date hereof and we assume no obligation to update or supplement it to reflect any change of fact, circumstance, or law after the date hereof.

Valero L.P. July 1, 2005 Page 3 In addition, our opinion is based on the assumption that the matter will be properly presented to the applicable court. Furthermore, our opinion is not binding on the Internal Revenue Service or a court. Finally, we must note that our opinion represents merely our best legal judgment on the matters presented and that others may disagree with our conclusions. Thus, there can be no assurance that the Internal Revenue Service will not take contrary positions or that a court would agree with our opinion if litigated. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm in the prospectus forming a part of the Registration Statement. In giving this consent, however, we do not hereby admit that we are within the category of persons whose consent is required under section 7 of the Securities Act of 1933, as amended, or the rules and regulations of the Securities and Exchange Commission issued thereunder.

Ladies and Gentlemen:

We have acted as special counsel to Valero L.P., a Delaware limited partnership
("VLI"), in connection with (i) the proposed merger (the "KSL MERGER") of VLI
Sub A LLC, a Delaware limited liability company and a wholly-owned subsidiary of
VLI ("VLI SUB A"), with and into Kaneb Services LLC, a Delaware limited
liability company ("KSL"), pursuant to the Agreement and Plan of Merger, dated
as of October 31, 2004 (the "KSL MERGER AGREEMENT"), by and among VLI, Riverwalk
Logistics, L.P., a Delaware limited partnership and the general partner of VLI
("VLI GP"), Valero GP, LLC, a Delaware limited liability company and the general
partner of VLI GP ("PARENT GP"), VLI Sub A, and KSL and (ii) the proposed merger
(the "KPP MERGER", and together with the KSL Merger, the "MERGERS") of VLI Sub B
LLC, a Delaware limited liability company and a wholly-owned subsidiary of VLI
("VLI SUB B", and collectively with VLI, VLI Sub A, VLI GP, and Parent GP, the
"VLI ENTITIES"), with and into Kaneb Pipe Line Partners, L.P., a Delaware
limited partnership ("KPP"), pursuant to the Agreement and Plan of Merger, dated
as of October 31, 2004 (the "KPP MERGER AGREEMENT", and together with the KSL
Merger Agreement, the "AGREEMENTS"), by and among VLI, VLI GP, Parent GP, VLI
Sub B, KPP, and Kaneb Pipe Line Company LLC, a Delaware limited liability
company that is the general partner of KPP ("KPP GP", and collectively, with KSL
and KPP, the "KANEB Entities"). At your request, and pursuant to Section 7.2(c)
of the KSL Merger Agreement and Section 7.2(c) of the KPP Merger Agreement, we
are rendering our opinion concerning certain federal income tax consequences of
the KSL Merger and the KPP Merger. Any capitalized term used and not defined
herein has the meaning given to it in the KSL Merger Agreement.


Valero L.P. Page 2 For purposes of the opinion set forth below, we have relied, with the consent of the VLI Entities and the consent of the Kaneb Entities, upon the accuracy and completeness of the statements and representations (which statements and representations we have neither investigated nor verified) contained, respectively, in the certificates of the officers of VLI, KSL and KPP dated the date hereof, and have assumed that such statements and representations will be accurate and complete as of the Effective Times (as if made as of such time) and that all such statements and representations made to the knowledge of any person or entity or with similar qualification are and will be true and correct as if made without such qualification. We have also relied upon the accuracy of the Registration Statement on Form S-4 filed with the Securities and Exchange Commission in connection with the Mergers and the joint proxy statement/ prospectus (the "PROXY STATEMENT/PROSPECTUS") contained therein, each as amended or supplemented through the date hereof. We have also assumed that (i) the transactions contemplated by the Agreements will be consummated in accordance therewith and as described in the Proxy Statement/Prospectus (and no transaction or condition described therein and affecting this opinion will be waived by any party), (ii) the Mergers will qualify as statutory mergers under the applicable laws of the State of Delaware and (iii) the Mergers will be reported by VLI, KSL and KPP on their respective federal income tax returns in a manner consistent with the opinion set forth below. Based upon and subject to the foregoing, it is our opinion, under currently applicable United States federal income tax law, that (i) no VLI Entity will recognize any income or gain as a result of the KPP Merger or the KSL Merger (other than any gain resulting from any decrease in partnership liabilities pursuant to section 752 of the Code), (ii) no gain or loss will be recognized by holders of VLI Common Units as a result of the KPP Merger or the KSL Merger (other than any gain resulting from any decrease in partnership liabilities pursuant to section 752 of the Code), and (iii) 90% of the combined gross income of each of VLI, KSL and KPP for (x) the calendar year ending December 31, 2004 and (y) the calendar quarter ending March 31, 2005 are from sources treated as "qualifying income" within the meaning of section 7704(d) of the Code. We hereby consent to the filing of this opinion with the Securities and Exchange Commission as an exhibit to the Registration Statement, and to the references therein to us. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended. This opinion relates solely to certain United States federal income tax consequences of the Mergers and no opinion is expressed as to the tax consequences under any foreign, state or local tax law or under any federal tax laws other than those pertaining to the income tax. We are furnishing this opinion to you solely in connection with the Mergers, and this opinion is not to be relied upon by any other person or for any other purpose.

Agreement"),  by and among Valero L.P. ("VLI"), Riverwalk Logistic, L.P., Valero
GP LLC ("Valero GP"),  VLI Sub B LLC,  Kaneb  Partners Pipe Line Partners,  L.P.
("KPP") and Kaneb Pipe Line Company LLC ("Kaneb  GP"),  you have  requested  our
opinion  regarding the U.S. federal income tax consequences of the Merger to KPP
and the KPP Unitholders  that are described  below.  Descriptions of the parties
and of the Merger and related transactions are set forth in the Merger Agreement
and the joint  proxy  statement/prospectus  forming  a part of the  registration
statement  on Form S-4 (Reg.  No.  333-120726,  as  amended,  the  "Registration
Statement")  filed on  January  25,  2005,  with  the  Securities  and  Exchange
Commission (the "SEC") by VLI pursuant to the Securities Act of 1933, as amended
(the "Act").  Unless otherwise  defined herein,  capitalized  terms used in this
opinion have the meanings assigned to them in the Merger Agreement.

In rendering our opinion set forth below, we have assumed that the  transactions
related  to  the  Merger  or  contemplated  by  the  Merger  Agreement  will  be
consummated as described in the Registration  Statement and solely in accordance
with the Merger  Agreement,  with none of the terms or  conditions of the Merger
Agreement being amended, waived or modified.  Additionally, we have examined and
relied upon the accuracy and  completeness,  both initially and continuing as of
the effective time of the Merger (the "Effective  Time"), of (i) the statements,
facts,  information,  evaluations,  covenants,  representations  and  warranties
contained in the Merger  Agreement,  the Registration  Statement,  including the
joint  proxy   statement/prospectus  that  forms  a  part  of  the  Registration
Statement,  and such other documents as we have deemed  necessary or appropriate
as a basis for the  opinion set forth  below,  and (ii) the  statements,  facts,
information,  evaluations,  covenants,  representations  and warranties  made or
provided by, or on behalf of, whether  written or oral,  KPP and VLI,  including
factual  representations set forth in letters dated the date hereof by Valero GP
and Kaneb GP (the  "Representation  Letters").  We have also  assumed  that such
statements,  facts,  information,  evaluations,  covenants,  representations and
warranties  are true,  and will  continue to be true as of the  Effective  Time,
without regard to any qualification as to knowledge or belief.  Any variation or
difference  in  any  of  the  aforementioned  statements,   facts,  information,
evaluations, covenants, representations,  warranties or assumptions or breach or
failure  of any of the  aforementioned  covenants  could  adversely  affect  our
opinion.

In  rendering  our  opinion  set  forth  below,  we have  considered  applicable
provisions  of the  Internal  Revenue  Code of 1986,  as amended  (the  "Code"),
Treasury  regulations  promulgated  thereunder  (the  "Regulations"),  pertinent
judicial  authorities,  rulings and other administrative  interpretations of the
Internal  Revenue  Service  ("IRS")  and  such  other  authorities  as  we  have
considered  relevant,  in each case, in effect on the date hereof.  It should be
noted that such laws, Code, Regulations, judicial authorities,

Kaneb Pipe Line Partners, L.P. July 1, 2005 Page 2 rulings and other administrative interpretations and such other authorities are subject to change at any time and possibly with retroactive effect. A change in any of the authorities upon which our opinion is based could adversely affect our opinion set forth below. Based upon the foregoing and subject to the limitations, qualifications and assumptions stated herein, we are of the opinion that, except with respect to cash received in lieu of a fractional VLI Common Unit: (i) KPP will not recognize any income or gain as a result of the Merger (other than any gain resulting from any decrease in partnership liabilities pursuant to section 752 of the Code), and (ii) no gain or loss will be recognized by holders of KPP Units as a result of the Merger (other than any gain resulting from any decrease in partnership liabilities pursuant to section 752 of the Code); PROVIDED, that such opinion shall not extend to any KPP Unitholder who acquired KPP Units from KPP in exchange for property other than cash. Our opinion set forth above is an expression of professional judgment, is not a guarantee of a result and is not binding upon the IRS or any court. Accordingly, no assurance can be given that our opinion set forth above will be sustained by a court if challenged by the IRS. Except as set forth above, we express no opinion to any party as to the federal, state, local or foreign tax consequences of the Merger or of any transactions related thereto or contemplated by the Merger Agreement or describe in the Registration Statement. We disclaim any undertaking to advise you of any subsequent changes of the facts stated or assumed herein or any subsequent changes in applicable law. This opinion may not be relied upon by anyone else without our prior written consent. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm in the proxy statement/prospectus forming a part of the Registration Statement. In giving this consent, however, we do not hereby admit that we are within the category of persons whose consent is required under section 7 of the Act or the rules and regulations of the SEC issued thereunder. Very truly yours, Fulbright & Jaworski L.L.P.
