1982 Corvette fuel pump failureS
Yes, failureS (plural).
I had a pump go bad so I ordered a replacement Delphi pump from a large parts distributor. Two days later, not remembering that I already ordered a pump, I placed another order for the same part from the same vendor.
Both pumps arrived. I pulled the old pump and installed one of the new Delphi on the pump / sending unit housing. I did the standard test, turning the key and listening to the pump. NADA, nothing, not a sound. I had already checked the power, and it read 12 volts plus for two seconds when I turned the key on.
OK, bad brand new fuel pump I am thinking. BUT, I had ordered two pumps by accident, which no longer looked like an accident.
I plugged in the second new fuel pump, turned the key on and heard a soft low pitch whine for two seconds coming from this pump. OK, lets give it a try. I got everything installed and went to test the pump. Turned the key on and NADA, nothing, not a sound.. I double checked power, fuses, etc. and all were fine.
i ordered two brand new 1982 fuel pumps and BOTH OF THEM turned out to be bad. How likely IS that?
OK, besides replacing the pump with dynamite, what do I do next? Different brand of pump? Modified fuel delivery system?
I really do no prefer to install an 85 fuel pump.

YES! Replace with the ACDelco 85-87 corvette pump. If you have 12v at the pump and the pump isn't working, it is bad for whatever the reason. Set the pressure at 13psi and you will be fine.
