I have an 1986 El Camino with a 402 big block. 750 cfm and a mild engine . It's not a big horsepower machine. Probably around 300-400 HP. I am replacing the mechanical fuel pump and wanted to know if there is really a difference between all these different ones you can get at local auto parts stores.
- Delphi Fuel Pump AMF0068
- Napa B0174P
- Carquest Premium 1542665

If you are going to use the factory hard line to the carburetor, carefully match the new one to the old one. The last new pump I got had the bottom clocked in the wrong position; I had to exchange it for another.

Other then that is that the only thing to watch for? I did not know if there was a different? The new one I looked at was exactly the same outside

If your car has a return line, you need the pump with 2 inlets and 1 outlet.

Delphi is the source of OEM pumps as far as I know.

Apart from that, get the one that has the best warranty.
