I had the exact same thing happen to me, only mine was a no start problem (My hose rotted right off) those Bosch OEM pumps are tough as nails, mine is the origional pump from 87. You might watch out though, mine seized up a few times while I was working on the tank. Just give it a few taps with a mallet and try to test it with a coffe cup of water. You should watch out about that though, they tried to get a new fuel pump out of me. After I got it unseized, I put it back in and its been working great since.
