Gas tank fuel filler hose cover sealant

[16again2009]

I just removed my gas tank. I remover the cover on the inside of the car that covers the fuel filler hose. I thought the sealant was going to be dum dum but it is not. It is rubbery and stretchy. Anyone know what it is?

16 … it’s something pretty funky and, I’d imagine, more on the industrial side, i.e., a product not easily found. As always, I could be wrong. When I put mine back together I used 3M Strip Caulk … dum dum.

Thanks John. I think I'll do that also.

Reminds me of butyl sealing tape, but I really do not know for sure what Porsche used.

it might be the same thing they use for body seams such as between the front fenders and the tub. very durable except when you have to replace a fender ad cant find the same stuff...
