Best/cheapest fuel pump for SPFI???


Recommended Posts

Ford Fuel Pump

part # 2p74028

NAPA

 

upon search for specs, it seems a bit high pressured. I would personally erase this doubt with another regulator by the current one, leaving in the original unhindered. The result pressure is in the low 20's OEM. original oem doesn't even trigger the euturn regualtor at spfi -- I did it very rarely, and then it made a hissing short noise like a blow off valve.It is to say a pump at 20 or even a bit less would still run the spfi, even lower than written specs.:) looks like it will fit right in, another usmb regular would know details.

The stock SPFI pump is capable of about 50 psi, but the regulator at the throttle body will step it down to 21. Anything that can put out 40-50 psi will work fine.

 

I would probably go with the Ford unit if you intend to use a new one. Personally I just used the stock one from my donor and that worked great for me.

I must have bad pump-- it doesn't even return anything back to tank. after taking things apart- it doesn't even look or smell like it ever had to .On another note- I have never encountered a spfi loyale that did:confused:

Crimp the return line from the regulator while it's running with a guage attached in the supply line and you'll be able to watch the dead-head pressure of the pump. Mine was right at 55 psi.

unfortunately, in my case there are no doner cars available for many miles around..a good used one as a spare would be the way to go and lot cheaper also...
