55' BA 235 6cyl stock.. My friends car had been sitting for a few months and when it started it ran until the gas poured into the carb was used up. The car has a 1/2 full glass bowl filter with no signs of new fuel going in. I removed the glass bowl and cranked the engine no fuel came out of the line toward the filter. I then put gas in the carb and it ran for a moment and still no fuel out of the line. Tank had fresh fuel and clean. I'm assuming a bad fuel pump or possibly clogged fuel line. Whats a good way to test the fuel line? I haven't cracked open the fuel line yet only removed the glass bowl thanks |

I would disconnect the front hose from the pump, the one that leads to the bowl, and turn the car over. looking for gas coming from the pump directly. also, blow air from the disconnected hose to verify clear line from the pump to the carb. next I would replace the pump, it was the only thing wrong with mine when i picked up. As i remember it was fairly cheap ($20-$40). But that was a yr ago or so now... now all that remains is testing the line from the pump back. its not the whole puzzle, but its a large piece. hope this is helpful. just checked, $38.99 stock replacement at autozone for blue flame 6, inline electric pump is $62.99... |

Before you replace the pump, remove the inlet line from the pump and crank the engine with your finger over the inlet fitting of the pump. If you feel a vacuum pulling on your finger, the pump is probably OK and you have a leak in the line from the tank to the pump. A small rust hole in the line will allow the pump to suck air and never pull any fuel from the tank into the line, so you won't see a fuel leak. Usually the rust hole is at the lowest spot of the line where water will collect on the inside.

Unscrew the line at the pump and the tank and blow compressed air through it. GENTLY blow air through the pickup, listen for air at the filler neck with the gas cap off. Could be that the sock at the end of the pick-up tube is plugged up with varnish. We have several Tri-Five clubs in S.D. county. I belong to Classic Chevys of San Diego, also know a couple guys selling parts. PM me and we can trade phone numbers and info. I do work swing-shift... Good Luck, Tim
