Fuel pump bad?

[Tulsa76bronco]

I have a carter pump which seems to be working fine. How can I tell if it is pumping enough fuel to my Holley 4 barrel 660 TA. I have two filters in between the carb and pump which were filthy. TAnk was new 8 years ago so I didn't think it should be that dirty. It did sit for about 5 years in my buddies garage

Any ideas

If you have 7 psi at the carb as measured with a gauge and it doesnt starve for fuel at WOT should be good. Fuel line at 3/8" sure helps.

Replace the filters then disconnect the fuel line at the carb and point it into an empty catch can. Pull the coil wire so engine doesn't start when cranking the starter. When cranking if the pump causes strong, pressurized gas streams coming out the disconnected fuel line then pump is okay.

I had a similar issue in mine. Does it run at all? Do you have 2 tanks? Looks like you do from your icon. Mine started just fine, sat for a bit, and then no go. I tried about everything. all new filters, I even swapped to a new fuel pump. It would start off carb cleaner or gas down the carb. I could suck fuel to the pump from the tank and fill the fuel line to get it to run but it would lose prime within a relatively short time.

The problem ended up being that something went wrong or dried out inside my tank selector valve allowing air in the line. bypassed the line and everything worked.

And what 661 buster said. If your carb is using too much fuel it would run for a short time until it ate all the fuel in the float bowls. Then it would die and turn over until the bowls were full, start and repeat. if tested at rpm.

Good luck, let us know what happens

Thanks guys well it ended up being a faulty wire at the pump it wasn't staying connected once that was tightened properly and the greese cleaned off it worked fine. Now I just need to send back the new carter I had overnighted. At least it was only 6$ to overnight it

Glad you figured it out. Doesn't hurt to keep as a spare.
