         Re:  Equity Issuance from Shelf Registration Statement on Form S-3

Ladies and Gentlemen:

     We have acted as  special  tax  counsel to  Ferrellgas  Partners,  L.P.,  a
Delaware limited partnership (the "Issuer"),  in connection with the preparation
of (i) the  Issuer's  Registration  Statement  on Form  S-3  (the  "Registration
Statement"),   as  filed  with  the  Securities  and  Exchange  Commission  (the
"Commission")  on May 21,  2004,  related to the  offering and sale from time to
time of 1,528,104  common units  representing  limited partner  interests of the
Issuer ("Common  Units") and (ii) the prospectus  contained in the  Registration
Statement (the  "Prospectus").  In formulating our opinion referred to below, we
have  participated  in the  preparation  of the  discussion  set forth under the
heading "Tax Consequences" in the Prospectus.

     As special tax counsel to the Issuer, we have examined, reviewed and relied
upon originals or copies, certified or otherwise identified to our satisfaction,
of (i) the  Certificate  of  Limited  Partnership  and the  Fourth  Amended  and
Restated Agreement of Limited Partnership of the Issuer, (ii) the Certificate of
Limited  Partnership  and the Third  Amended and  Restated  Agreement of Limited
Partnership of Ferrellgas,  L.P.,  (iii) the  Registration  Statement,  (iv) the
Prospectus,  (v) particular resolutions of the Board of Directors of Ferrellgas,
Inc., the general partner of the Issuer (the "General  Partner"),  and (vi) such
other documents, faxes, certificates,  instruments and records as we have deemed
necessary,  desirable or relevant for purposes  hereof.  We have also  examined,
reviewed  and  relied  upon  certain  representations  made by an officer of the
General Partner  relating to the Issuer's  organization  and actual and proposed
operation as well as to certain  other  matters of fact relating to this opinion
and  have  made  such  investigations  of law as we have  deemed  necessary  and
relevant as a basis hereof.

     In  our  examinations  and  investigations,   we  have  assumed:   (i)  the
genuineness of all signatures on, and the  authenticity of, all of the foregoing
documents,  faxes,  certificates,  instruments  and records  (collectively,  the
"Documents")  submitted to us as originals  and the  conformity  to the original
documents,  faxes,  certificates,  instruments and records of all such Documents
submitted to us as copies;  (ii) the  truthfulness of all statements of fact set
forth in such Documents; (iii) the due authorization,  execution and delivery by
the  parties  thereto,  other than the Issuer and the  General  Partner,  of all
Documents  examined by us; (iv) that,  to the extent such  Documents  purport to
constitute  agreements of parties other than the Issuer and the General Partner,

such Documents  constitute  valid,  binding and enforceable  obligations of such
other  parties;  (v) that all terms and  provisions  of such  Documents  will be
complied with by all parties thereto and are enforceable  under  applicable law;
and (vi) that the information presented in such Documents or otherwise furnished
to us accurately and completely describes all material facts. No facts have come
to our  attention,  however,  that would  cause us to question  the  accuracy or
completeness of such Documents,  or the facts contained  therein,  in a material
way.

     Based on the  foregoing  and  subject to the  limitations,  conditions  and
assumptions   set  forth   herein,   and   having  due  regard  for  such  legal
considerations  as we deem relevant,  the statements set forth in the Prospectus
under the heading "Tax  Consequences,"  to the extent that they constitute legal
conclusions and subject to the qualifications set forth therein,  constitute our
opinions as to the matters set forth therein.

     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.  In
giving this consent,  we do not admit that we are "experts,"  within the meaning
of that term as used in the Securities  Act or the rules and  regulations of the
Commission  issued  thereunder,  with  respect  to any part of the  Registration
Statement or the Prospectus, including this opinion as an exhibit or otherwise.

     The foregoing opinion is strictly limited to the matters stated herein, and
no other or more  extensive  opinion is  intended  or implied or to be  inferred
beyond the matters  expressly stated herein.  The foregoing  opinion is based on
and is limited  to, as in effect on the date  hereof,  the  federal  laws of the
United  States,  and we render no opinion  with respect to the laws of any other
jurisdiction or, without limiting the generality of the foregoing, the effect of
the laws of any other jurisdiction.

     Our opinions  expressed  herein are also based on the Internal Revenue Code
of 1986,  as  amended,  Treasury  regulations  promulgated  thereunder,  and the
interpretations  of the Code and such regulations by the courts and the Internal
Revenue Service,  all as they are in effect and exist as of the date hereof.  It
should  be  noted   that   statutes,   regulations,   judicial   decisions   and
administrative  interpretations  are  subject to change at any time and, in some
circumstances, with retroactive effect. A material change that is made after the
date  hereof in any of the  foregoing  bases for our  opinions  could  adversely
affect our conclusions.

     It is understood  that this opinion is to be used only in  connection  with
the  offer  and  sale  of  those  particular  securities  described  within  the
Prospectus  while the  Registration  Statement and the Prospectus are in effect.
Other  than as  expressly  stated  above,  we  express  no  opinion on any issue
relating to the Issuer or to any  investment  therein.  The  opinions  expressed
herein are as of the date hereof,  and we undertake no  responsibility to update
this opinion after the date hereof and assume no responsibility for advising you
of any changes  with  respect to any matters  described in this opinion that may
occur subsequent to the date hereof or with respect to the discovery  subsequent
to the date hereof of  information  not  previously  known to us  pertaining  to
events occurring prior to the date hereof.
