Thread: Where is the fuel going? '73 "FE"250 truck

Tweet

take the top off the carb and look before starting----


Old truck, probably no cranking vacume and empty carb

Thanks all, the fuel filter before the carb was full this morning, and I pumped the acc. linkage and saw no fuel squirting int othe carb.

I could here the rubber diaphram rubbing though. the fuel filter I have before the fuel pump was almost empty.

I will tak the top of the carb off in the morning and see what is or is not there.

As an aside, this truck runs strong, it is still pulling hard @ 90MPH, it has a 4 spd NP435 i think.

If the fuel line / filter is full, but no gas was being pumped in when working the throttle, I'd say the accelerator pump has failed. Let's see what you find when you remove the top. There is a small port that keeps the accellerator pump reservoir full, maybe theres debris over that and the pump is being starved?!?!
