the chevy is suffering from fuel starvation.
I'm not using it at the moment, just up and down the drive manovering to work on it and stuff.
It will start fine and run ok, if started regular (as in every other day)
leave it more than a week and i need to prime the carb and fuel line with petrol to run the engine long enough to draw fuel from the tank. Either that or disconnect the pipe at the lift pump inlet and syphon the fuel to that pint. Both option are a pain in the arse when all you want to to is move the car to get at something. Everything is working, it's just that the fuel seems to have ran back to the tank and the pump isn't man enough to draw fuel past the low point in the main fuel pipe
The fuel pipe from the tank is pretty long and has a low point due to the path it has to take.
any suggestions as to how to prevent this? check valve put somewhere in the line? at the fuel tank end?
