I agree.

To the OP:

Try to verify it is a fuel delivery problem. Mechanical pumps either work or they don't. If they fail, they spray gas out the atmospheric vent hole side of the simple diaphragm body.

Fuel delivery issues with a mechanical pump that does not have a bad diaphragm, points to restriction/blockage upstream of the pump. (between pump and tank or tanks)

Often times there are inline filters between the tank and pump, if those become plugged then the pump will starve. Kinks in hard lines, old soft line pieces at the tank outlet, screen sock on the pickup tube inside the tank on the sending unit.

.After the truck runs out the gas he poured down the throat, the truck continues to run and run good.Doesn't that negate and blockage question.


The OP just manually fueled the carb...............


Here is what he posted:

If I pour gas straight into the carb it'll fire up and usually after one try, almost always after 2 then it'll keep running after it burns up the gas I pour in.

I agree pal. Guys that don't know how to work on vehicles tend to unnecessarily throw money at a nonexistent problem vs. fixing the real problem....
