I see with your great pictures.It would be nice to have that nifty tool but I am doing the drip test method with high pressure. easy enough. I am assuming the lift pump is moving fuel from the tank and I see it is driven by a cam inside the pump on my old pump on the bench. I will try to pull the pump out today and see if the collar assembly is lined up with the mark on the flange. Previous owner had removed the vacuum pump for some reason and maybe he screwed up the injection pump timing. Is it possible to test the function of the cam driven lift pump? Does it have a rubber diaphragm or a piston setup.? It is a thrash getting to all the nuts holding the pump. I'll be in touch. If it doesn't start and run I guess it is a bad lift pump or lousy compression. After that I am out of ideas. Thanks
