I guess rebuilding isn't the correct verbage, but that's what I have found most on this site to describe what I have done. I bought what I would call and O-Ring kit with a few other parts in it. This was a part number something like 23471 if I remember correctly.
To start with this grader had sat for a couple of years without being used. When it would start, I checked the fuel and I didn't get anything out of the bottom "OUT" connection that goes to the fuel pressure gauge on the grader. I also removed a couple of the injector lines and didn't get any fuel out of these either.
I completely disassembled the pump and throughly cleaned and inspected according to the manual I purchased for the Roosa DB pumps.
I assembled the pump with the new o-rings and etc and re-installed it on my grader. The grader started right up and ran fine for a few minutes and then died like it ran out of fuel. I can start it back up and it will run for a few seconds and die again.
I ensured that it had fuel and went as far as putting a couple of new fuel filters on it just to be safe (even though the fuel pressure gauge was reading around 80 when the unit started up for the short time).
I removed one of the injector lines and I have good fuel being pumped out of the pump when the unit starts.
What I don't have is any fuel returning to the tank, not from the injectors nor from the return on top of the pump.
I did check the oil and the level has gotten pretty high, so I can only assume that the shaft seal is suspect on that part, but I don't understand why I am getting fuel to the injectors but nothing from the injectors!?!?
Attached is a picture I made that may help me explain what I have going on right now...
