I have changed the fuel filter, changed the fuel in tank, replaced selenoid, prayed and wept a little. I have manually filled the line from fliter to injectors and it will run until that fuel runs through, but no fuel moving from filter housing into line. The filter housing is full of fuel by me. Any advice would be apreciated.

either your screen is plugged in the tank or the fuel pump is so worn it has zero suction.

You know it has a little primer lever too. Try pumping it for a minute or so to see if it will prime.

And now you know why you need to head bump a concrete wall whenever you run a diesel rig out of fuel. ....thats why diesel rigs usually come with 2 battery's.
Ive had fits like that as construction maintenance on many diesel rigs after draining the water separator....the fuel pump is so weak it will not connect HG vacuum with the tanks to suck the fuel up.
Yes I do. And have tryed pumping it often and for long periods.

Pull the lines off the lift pump#5.. have someone spin the engine.. FEEL if its sucking one way & blowing the other..
IF SO.. reinstall the lines.. MAKING SURE they go on the correct way..
Loosen the return line banjo bolt on the injection pump & Pressurize the fuel tank w/ a little shop air..
Spin the engine while doing this.. the air should be dispelled & fuel should come out of the loosened return line bolt.
Tighten.. NOW, loosen the lines AT THE INJECTORS & spin the engine until fuel squirts out & tighten..

Didnt run out of fuel. It just idled down and to a stop like being out of fuel, but i noticed when i drained the tank thinking it might be water in the fuel that it was not out of fuel.
