I have been speaking to a buddy that has a frame mount electric fuel pump off of a powerstroke that he had suggested I use to create an electric system with external mounted filters and water separator. I am reading mixed about these pumps however. He tells me they put out about 70psi and I am concerned that would be too much pressure even with the adjustable OFV. I would think that with the reliability and more constant flow as opposed to the pulsing of the cam driven LP that this is a good option if the pressure is not too much. Any thoughts?

 

a powerstroke needs 50-55psi. if it is an air dog or fass you should be able to turn the pressure down to an acceptable level. i run in the 35-40psi range. i wouldnt want to run much higher for extended periods.

 

Yeah that kinda pressure would not do your IP much favors ..

 

I don't understand why people go away from the stock 2nd Gen lift pump.

 

Okay thanks that means I would need a regulator of some kind

 

I have not gone away. I even have a spare. I am just looking at options at this point.

 

because some of us need the volume of an electric pump. but from stock to 350ish hp applications it is silly to do away with the stocker. and you may not need a regulator. install a mechanical gauge on the top fort of the air dog and check to see what the pressure is. turn the jam nut out and see how low you can get the supply pressure to fall to.. if it is to high then you will need a regulator.

 

I don't have access to an airdog just a Ford Powerstroke pump.

 

an OE 6.0 liter pump? i guess later model 7.3L had electrics too. anyway in that case yes, you will need an regulator

i personally wouldnt fool with it however if the stock lift pump is working properly, your after volume not necessarily pressure. more headace than its worth.

 

Thanks I was looking for input either way.
