I suspect they treat the paper gasket with an anti-poop chemical that eats the stud. I've gone to an industrial supplier and for very little money have bought SS threaded rod the same size, cut it to length and replaced all the studs on brand new pumps before installing.

If you have one of these pumps installed on your boat and it quits pumping, chances are a stud or two have come apart. Don't ask how I know this. LOL. Easy to fix with that SS rod.

The company is sending me stainless steel bolts to repair this. I should have asked for two sets. One for the working pump and one for the spare.
