Re: Best Fuel Sender Gasket Source
Parts are in.
Gasket and cam are both contributors to the leak condition. GM gasket is .235" thick. I have two aftermarket gaskets, .015 and .020 undersized. I was expecting the leaking gasket that was removed would be swollen and soft as I am always suspicious of unregulated materials outside of GM control. However, it seemed to be sufficiently fuel resistant after 4 months exposure. Good formulation, just undersized.
Bigger contributor is the retainer cam. See photo. GM part on the right ramps outward to present .090" of compression on the gage mounting plate. The aftermarket piece has no ramp, just the retaining bump, so final compression is no more than the material thickness of .050".
So combined the aftermarket pieces fall short .060". That's a lot to give up. One might get by with a skinny gasket and a GM cam but I'm glad I found both OE parts. Looking forward to leak free operation.
