stripped sending unit screws in plastic tank

Yup, surprisingly delicate assembly given the importance of that fixture.

Like using string to connect to wrecking ball.......not enough hardware.

Got lucky myself by tightening with wrench.........the screwdriver head slot won't allow enough torque...

Total assembly connection to gas tank should have been much more robust.

Isn't that why they make non-hardening Form-a-gasket? I never put in a gasket without first coating the surfaces with that stuff. (Head and exhaust gaskets excepted). You don't need excessive torque when using it, and it's gas and oil resistance makes it idea for applications like this.

I get seepage around the sending unit if I overfill the tank for that very reason. Once I burn off a few gallons it stops. I literally just resorted to using a fuel rated form-a-gasket. Haven't totally filled the tank yet so I can't comment on whether it worked or not. Will report back on this thread.

Performance against plastic ?

No problems... only thing you need to be careful of is high heat (above 600Deg) So no exhaust fittings or the like.
