1956 M135 Fuel Pump PSI

[hungryhungarianz]

I need to know what pressure the old existing fuel pump runs at? I tested it with a 2-4 PSI fuel faccet pump but it does;nt seem to deliver enough fuel.

As i need to modify it and purchase a 24 volt electric. But how many psi should it be?

Thank you

Fuel pressure GPH G749

I can smell an M135 thread a mile away, Welcome to the round nose rotunda. Found the data on page 227 over here on 9-8024, https://www.steelsoldiers.com/showthread.php?106483-More-M135-TM-s

2 1/2 to 3 psi , 20 gph ...... We test them with a jerrycan safely secured to a mirror so they don't need a lot of juice. Too much juice and a poorly set float in the carb can let gas flow through an open valve. Sometimes just enough gas flows that when it gets a spark it'll blow the muffler off. Let's be careful out there and carry a large fire extinguisher in your pocket.
