Ive recently started driving my 81 honda on a daily basis. It has a webber 32/36 carb and a frame mounted gravity fed fuel pump. Ive noticed that it will idle for hours no problem but after about 10 minutes of driving the fuel bowl will run dry and it stalls. Ive noticed that the fuel line from the tank to the pump has a couple of loops in it but I dont think that should affect the flow. ALso, the pump looks like it has a little bit of dried up fuel around it but that could be from small leaks over time. I cant find any current fuel leaks. Should I replace the pump first or rebuild the carb first? I think its the pump but a buddy of mine is a reputable master tech and says it needs new floats and a rebuild but hasnt actually spent any time with the car. any ideas?
