Ethanol resistant gas cap seal

[csmith]

FYI, I just went over to G5 at Rickf's suggestion and bought some gaskets from Jim Hybicki. He has Main Gas Tank, and 5 gal Jerry Can rubber ethanol resistant caskets available at Very reasonable prices. Jim can be reached at JAMESHYBICKI@aol.com
if anyone is interested. Price $3.90 for the first, $3.00 for additional including shipping, same price for both caskets.

Just for my knowledge .....

(1) why are they termed different
(2) Do the normal gaskets not hold ethanol back / Is ethanol capable of bypassing normal cap seals or is it a marketing gimmick
(3) Are these gaskets, rubber or leather
(4) Would leather perform the same function in sealing the cap as rubber does

Ethanol will make some types of rubber soft as well as swell out of shape. The gas cap gasket is usually where problems show up. I don't think all gas cap gaskets were made out of a type of rubber that reacts adversely with ethanol or more people would report problems. I don't think leather would work very long with the more modern cleaner burning types of gasoline that are made today.
