Its good the sol. works.. but u have to find out if the machine is putting the correct voltage to it..
That "bolt" is a plug for the timing tool u use to time the pump to the engine.
U tighten the lines ON THE PUMP & it really doesn't matter about the lines at the injectors.. but u have to be able to see the "drips".. The fuel needs to be squirting out w/ no air.. then tighten the lines..
The more lines u have loose, the faster the air comes out..
The problem I'm seeing is>> you've spun this over enough for the air to be purged.. so that tells me u got a pump problem..??
So u took the fuel system off of 1 engine & put it on another?? {not a good idea}
Just because they "looked the same", there can be a gazillion things that can be different.
Did it run on the other engine.??
Did u time both engines??
Was the drive shaft on the pump keyed.??
Regardless of the timing, it still should pump fuel..
Did u DE-GREASE & TORQUE the nut on the drive shaft.??
IF the dr. shaft is not keyed, it could be spinning in the gear & not fully turning WITH the gear.??
Just a few things "it could be"..
OH & don't forget about the fuel going INTO the pump.. 5psi
