Thread: 77 C20 fuel problem

Tweet

I use my 77 C20 to pull my 5th wheel. I have no problems with that. The problem is that when sitting a couple days the gas runs back out of the carb. It takes a while to pump it back up. I'm thinking of putting a check valve in line between the pump and the carb. There is one on the filter in the carb but I have tried several of them and they just don't hold. Another thought is to put a loop in the fuel line before the carb going above the carb and back down to the inlet. Anyone else have this problem? What did you come up with. 77 Camper Special 454 400 trans.

Quadra jet I have looked in the carb and its never wet. I suppose that could be what's going on. Its the original as far as I know

I have not but can try it. It says for 65/68 would my 77 be the same? I'll look around and see if I can find one for mine Thanks

guess I'll get some numbers off it and see what I find

Sorry it took so long to get back but wife been in and out of hospital and finally near ready to get out and go somewhere. I did take the carb apart and found a glue of sorts on the plugs. I cleaned all the old stuff off and replaced it with JB weld. After that It was doing the same thing the po told me he had replaced the fuel pump but It just didn't get the gas up very fast. So replaced that and now were running great. It sits for weeks now and fires right up. Thanks guys

Charlie, I hope all is well with your wife! Glad to hear you got your truck fixed.
