I'm having problems with my Fuel Pump, it's a single tank and the motor is the 300 cu inline six with 188,000 miles on it. The first time it would not start (could not hear it run) we dropped the tank and put the pump on the bench, hooked it up to a battery and it worked. Put it back in and it didn't work. Being it's a "Rusty but Trusty" truck I cut a hole in the bed and pulled out the pump from the top, went and bought a new one from Advanced Auto (got the life time one), put it in and it worked for about three months. It again failed the other day, had my son bring over his Rollback to take it out to his place to work on it, said I'd try it again (about an hour later) and it worked. He use it for a few days and it wouldn't run again, pulled it back out and cleaned up all the connections, it worked again. Now it's only a Rusty truck, can't Trust it any more.

My son talked to a Ford mechanic and he asked what kind of pump, he says it's the pump, that's there must be a flat spot and whenever it shut off and hits that area it wont start. He said that it happened to him with a brand new Ford pump and that they just beat the bottom of the tank with a rubber hammer until it worked.

Any suggestions?
