Re: Do mechanical fuel pumps get weak?

There's a diaphragm as mentioned, and you could get a hole in it and it'd pump a little but not well. Still, unless I'm confused with the water pump, I thought the fuel pump had a weep hole such that if it ruptured or leaked it'd leak out the body of the pump...
