Fuel Problem Don 3-27-15  
I have a 1984 Pace Arrow 454 on a P30 1983 chassis. Mechanic ran the engine until it was out of gas. Now there is no fuel to the carb. I replaced fuel pump. No luck. I can pump gas from the tank to the carb with a manual pump, but when I replace the line the engine pump will not supply fuel.

Guess: WHen installing the GM 454 fuel pump there is a little push dod that activates it. If the pump is not installed carefully so the rod pushes correctly on the pump lever the pump won't work.

Usually miss installing the pump ruins it when the bolts are tightened up.

Or you have a leak on the intake side of the pump.

Good Luck

OOOPS I may have steered you wrong.

When you pump out of the tank to make it run you dont use the same pick up or supply plumbing as the engine mounted pump do you?
If you use the original plumbing for that test just ignore this.

If you dont, it is very possible, in fact quite likely the pick up filter inside the tank, its called a sock, is plugged. Common when old tanks run ou of fuel, all the crud in the bottom sloshes into it.

The test is: using a vacume guage adapted in the system run the engine mounted pump. The pump may make only 3 or four inches of vacume, but if it makes any without fuel flow the Filter sock or a fuel filter between the tank and pump is plugged.

Good Luck
