I've heard of the potential trouble with the mech. fuel pump so I'd like to switch it over to an electrical one. My question is at the parts stores they have asked me how much psi and how many gallons per hour I want, I don't have the foggiest idea what to tell them. Any help would be great, also any install tips would also be great. Thanks.

Stock is about 4-7psi and 30gph.

I'm running a Facet Dura-lift in mine, which is a commercial grade pump designed to run 24/7 and I now have a contact to get them for a great price.

 

where should you mount the pump. Did you leave your mechanical pump on too? and also how do you have it wired. im doin the same i want to get my fuel problems stopped before winter hits. thanks justin

 

You should remove the stock pump, just use a Chevy 454 block off plate. If you try to run both, the diaphragm in the stock unit can rupture and fuel will fill the crankcase. You can also leave the stock pump on the engine, just disconnect it from the fuel lines.

I mounted mine in the engine bay, but you can mount it down on the frame after the selector valve. It should be wired through a relay that's switched on with the ignition. It will also make bleeding the system much easier.

 

what is a good brand of pump? i found one at oriellys for 50 bucks or so and it is like 5-9 psi and about 30 gph would that work?

 

Some use Holley reds, Facets (small type), Carters and all those are pretty much for gasoline only. They will pump diesel but I've heard of a number of them going belly up. The Dura-Lifts are commercial duty and for diesel so I shouldn't have any problems.

 

I have my Facet Duralift pump mounted on the frame, just forward of the selector valve. I have had zero fuel delivery problems since putting it there. It's a darn good pump... Especially for the price!

The best pump that I have found is the same basic one that was used on the olds 5.7 Diese. It's a solenoid pump that you can push fuel through. I think the number is E12. ABout $50.00 at autozone. I have one installed on my 7.3 F350. It is installed on the fuel line between the mechanical pump and the fuel filter. I use it to prime my system. I mounted a switch on the dash to control it. It only draws about 3-4 amps. AC had one of these pumps running for over 10,000 hours before they terminated the test. The only thing that will kill it is stringy contamination and reversing polarity.

 

Do you use this fuel pump inconjuctoin with the factory maual pump?

An electric pump before the manual pump is asking for trouble.

If the manual pump diaphram leaks, the crankcase will be filled with fuel.
Either the oil pressure falls or the crankcase runs over before you know what is going on.
Engine damage is very possible.

 

DAVE S. what kind of pump do you use???

 

I have a stock lift pump.

As a matter of fact, I am still using the original after 431,000 miles.

 

THANKS DAVE...
Why no electrical pump???
