One thing to point out for any future people: you aren't going to push fuel through the IP without cranking. The inlet of the IP goes into a positive displacement vane pump, which obviously isn't going to pass much of any fuel unless it's spinning.

Pump. Iam never too old to learn something new. The Lift Pump only transfers fuel from the tank to the engine with a low amount of
PSI. The IP then increases the fuel pressure to 1800 PSI or more (depending on engine type) to the Injectors to over come the POP
pressure the Injector is set to. There is a stiff spring in the injector along with Shims to adjust the POP Pressure so they are balanced.
My first Diesel was back in Oct 81 (still have it) and have owned Diesels ever since. Wow almost 38 years,
and Iam not even that old yet....
