         Re:  Equity Issuances from Registration Statement on Form S-3

Ladies and Gentlemen:

     We have acted as special 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 the
date hereof pursuant to the Securities Act of 1933, as amended (the  "Securities
Act"),  related to the offering by or for the account of the selling unitholders
named  therein  (the  "Selling  Unitholders")  of up to  1,528,104  common units
representing  limited partner interests of the Issuer (the "Units") and (ii) the
prospectus contained in the Registration Statement (the "Prospectus").

     As special  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  of the Issuer,  (ii) the Fourth
Amended  and  Restated  Agreement  of Limited  Partnership  of the  Issuer  (the
"Partnership Agreement"), (iii) the Registration Statement, (iv) the Prospectus,
(v) particular Unit Purchase Agreements each dated February 8, 2004 between each
of the Selling  Unitholders  and the Issuer,  (vi) a Real Property  Contribution
Agreement  dated February 8, 2004 between one Selling  Unitholder and the Issuer
(the Unit Purchase Agreements and the Real Property  Contribution  Agreement are
hereinafter referred to collectively as the "Unit Issuance  Agreements"),  (vii)
resolutions of the Board of Directors of the general  partner of the Issuer (the
"General Partner")  regarding,  among other things, the Registration  Statement,
the  Prospectus  and  the  Unit  Issuance  Agreements,  and  (viii)  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  certificates  of officers of the General  Partner and
faxes and  certificates  of public  officials,  as to  certain  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 and (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.

     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,  we are of the opinion  that the Units are
duly  authorized,  validly issued and, on the assumption that the holders of the
Units take no part in the control of the Issuer's  business and otherwise act in
conformity  with the  provisions  of the  Partnership  Agreement  regarding  the
control  and   management   of  the  Issuer,   the  Units  are  fully  paid  and
non-assessable  (except  as  non-assessability  may be  affected  by  particular
provisions  of  the  Delaware  Revised  Uniform  Limited  Partnership  Act  (the
"Delaware Act")).

     We hereby  consent  to the  filing of this  opinion  as an  exhibit  to the
Registration  Statement,  and to the reference to us in the Prospectus under the
caption  "Legal  Matters." 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  Delaware  Act,  the
General Corporation Law of the State of Delaware, which includes those statutory
provisions as well as all applicable provisions of the Delaware Constitution and
the reported judicial decisions interpreting such laws, and the relevant Federal
law of the United  States of America,  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.

     It is understood  that this opinion is to be used only in  connection  with
the offer and sale by the Issuer of the Units 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.

                                   Sincerely,
