Lift Pump

[Diesel Freak]

Looking at putting a 12 valve mechanical lift pump on my truck.

Does anyone know how much fuel they will move??? I know I will need a regulator.

By my calculations, at 50 psi it flows somewhere between 80 and 85 GPH with a pusher pump force feeding it 10-15 psi.

While I don't know any specs Cliff I can tell you from experience it is strong enough to pump out more than 1/8 tank of fuel in only a mile or so, when the fuel line to the injection pump broke in two in the middle of Nebraska. And even though the fuel line completely broke in half it pumped enough fuel past the break to keep me motoring along as though nothing was wrong, towing a car on a flatbed.

Shouldn't be a problem feeding a vp44 Cliff. I have to get into my 13mm pump pretty hard to take the stock piston pump down below 25psi.
