fuel headache

[DASBRONCO]

Hi guys, im here again with my bronco making me pull my hairs. my 79 bronco cant seem to deliver fuel to the carb, it stalled when running on the highway, i opened the hood and the fuel filter empty. when she felt like starting i would get home. first thing i replaced was the fuel pump for a carter unit, it didnt work. next i relaced the carb's float-seat-valve in the bowl, id didnt work either. i went crazy and bought a sending unit and dropped the gas tank, and flushed the fuel lines. i found the tank was really clean so i had it flushed and put the sending unit in, it also dodnt work. after all this i was determined to tackle another fuel pump swap, i replaced the carter with an AIRTEX unit, and now i cant even go to the hardware store cause the carb will dry out before i get there. i dont know what else to do, please can anyone help? i really love my girl and she's the only ''sunburst'' free wheeler i have seen with al the goodies, even ruise control. she is a beauty. please....anybody have this happen to them?

Hi DAS..,

WOW..! That is odd.

You may have a leak of sorts in the fuel line (between tank & pump) in that it sucks "IN" air, thus lessening the amount of fuel being sucked by the pump.

The only parts in that system are; the tank, pick-up tube, lines, switching valve, (if that rig has one) & the fuel pump......??

In rare cases a rubber gas line can seperate & suction causes it to colapse internally.

Another rare but poss. The cam lobe that runs the pump may be worn down & not giving a full stroke to the pump.

You could bypass the pump with an electric pump & see if that cures it.

HTH
