PR-1750-A is the only flexible tank sealant that is advertised as
ethanol resistant. It is made by Able Aerospace, ph. 661 257 2500.
Because of its short shelf life it is made to order and is rather
expensive. When I bought some, it was $165 / qt but smaller quantities
are available. Other sealant is fairly ethanol resistant:
Jeffco 9700 (grey), gets very hard, only for tank structure, not for
sealing end plate
Dark purple, polysulfide elastic sealant (Chemseal CS 3204, A-C-Tech
AC-236, PR-1440., spec: AMS-S-8802)

Bernie, hope you get the tank problem cured, it will not be a lot of fun.
You will have to devise something to reach all the way to the end of the
tank to spread the polysulfide.
Will you be driving out to Kansas or flying? That is one long drive. We are
starting to plan a year long trip in our motor home, starting in October
with a run to Texas. We plan to be on the east coast part of the winter,
maybe Myrtle Beach. Do you guys go south for the winter? It would be fun to
meet up somewhere in the warm climate.
Anyway, sounds like you are doing well and in good health. Looking forward
to seeing you in Lawrence.

Today I drained out some fuel from my Pulsar after the plane had not
been fired up for about seven weeks.
The fuel was a light amber color.
I assume that ethanol is beginning to dissolve the coating in the fuel
cells.
What is the latest recommendation for fuel cell sealant that is
resistant to ethanol ? ? ? ?
Thanks in advance for the recommendations.
Benie Wilder
P.S. See Y'all (( Or some of you. )) in Lawrence.
