I have a small leak coming from the right wing fuel tank sender. Looks like the original builder put in the sender and used the rubber gasket rather than proseal and no gasket. I plan on fixing it by removing the sender while the tank is still in place.
My question is about the screws that hold the sender in. When replacing the screws with the new sender, how are the screws themselves made from leaking? Are they prosealed as well? Do you apply proseal to the holes or screws themselves, then screw in? Or does the ring of sealant place around the flange of the sender somehow take care of this on it's own? I will not have access to seal from inside the tank.
I've researched this some and haven't found a definitive answer and want to do this job the right way, once.
