That sheet will become a gooey meltdown mess.
Here's one look at materials compatibility with ethanol (A.K.A.) and gasoline.

"Kalrez," is the clear winner here, is a DuPont name for perfluoroelastomer (FFKM). The stuff is made in sheets.
If you can find it reinforced with Kevlar (again, a DuPont name for para-aramid fiber) you will have a winner!
I need a sheet of this for my B pumps!!
Also of interest on this chart is "Viton," that wonderful (Ha!) stuff on many needle valves.
Not too good with ethanol!Mechanical engineering 101: If you put an adjustment knob, screw, bolt, or tolerance specs on something, some people will immediately fiddle with it. If you mark it DO NOT TOUCH everyone will mess with it.
