old dog is a Soldier
Default no fuel to carb

Took off fuel in line filter and cranked engine, no fuel coming out of line, prior to me pulling the fuel pump any other way to check why no gas coming out of line when cranking engine??? limited knowledge mechanics but have owned many military vehicles and a few M-715s, and would never sell the 715, have a complete engine spare and could exchange out fuel pump but prior to that any suggestions would be appreciated.........thanks......

IIRC the fuel pump diaphragm may be cracked or the intake sock in the fuel tank may be clogged, or both. You could put the gas tank line in a fuel can and see if it pumps or not. I never had a tornado in my truck, it was already swapped out. A plugged fuel tank sock is not uncommon.

Default Fuel pump rebuild

Then and now automotive
tel:781-335-8860
They can supposedly rebuild it with a diaphragm that better handles ethanol fuel.

Yes, ethanol resistant parts.
I have used one of their kits for my truck's fuel pump.
The instructions in the kit are really detailed, pretty easy to do.
