best sealer for fuel tank sender??

Iam looking for the best sealant to use to seal the fuel gauge sender unit on my 1957 truck? Thanks moparts!!

Rubber gasket. Find one or make one.

Wont the ethenol in todays fuels eat at the rubber?

It didn't hurt the gasket in my '64Dog.

Use a material that is resistant to ethanol and gasoline when you cut your gasket.

R.

Not with the proper rubber.

Is the sender bolt in? Or ring clamp style like the later cars?

Either way I would buy or make a gasket. Sealant and gas do not get along well and hard to get a durable seal w/o gasket. Good clamp on a gasket is the best with a thin coat of aviation sealer if the sealing surfaces are a bit rough.

thanks for the replies. It is the old school type ring clamp.

The gasket for a 60's/70's car type sending unit is available if yours is the same.
