OK after lurking for a while here's my first post.

Repairing 2 fuel leaks at the o-ring seal on the fuel delivery valve. Replaced all 3 o-rings and the copper washers at the barrel as well. NO more leaks, but now, I can't get enough fuel or pressure to my injectors. Plenty of fuel to the valve, but little to none coming out to the line. Bled all the air out of the system getting a little fuel up to the injectors but still runs like manure.

Is there some trick to reinstalling the delivery valve assembly on this injection pump??

Did you pull the entire Injector assembly out or just the delivery valves?
To what extent did you pull it all apart?
Did you clean every part thoroughly?
If you remove the lines to the injectors can you get the injector pump to pulse the same amount of fuel out each delivery valve?
Is it possible that contamination has now plugged the injectors?
Have you pulled/cleaned the injectors?
Sounds to me like you didn't get either the delivery valve in right or some other part, or possibly dirt got into it and is plugging up the works.

Just removed all the parts from the top.

Have cleaned and cleaned reassembled at least 20 times. I can get a pulse on 2, but not all 3.

This tractor ran great before.
