[QUOTE="bobbie-g, post: 1162, member: 26"] I had all the fuel line components replaced, from inside the tank clear up to the injector pump. But I still get air in the line when I shut down for a few minutes (ranges from 3 minutes to 15 minutes). Looks like that clearly puts the problem in the injector pump. Shane, how does the air get in? It must come back through the overflow line? I remember overflow lines on each of the injectors, and I think I remember one on the pump itself. Thanks for the warning about not putting an electric pump in line. I don’t see how fuel would get to the crankcase, since the injector pump is not physically connected to the crankcase. It’s bolted to a flange with two bolts, and the drive gear is driven by the timing belt. Could I get away with an electric pump with a momentary switch, so I could just bring up the pressure (4 or 5 psi) as I try to start it? ---- And does anyone have a clue where I can get an injector pump for less than $1000? -------------------------- Tnx, ---Bob [/QUOTE]
