I just had my Roosa Master injection pump rebuilt by professionals. When I mounted it on my tractor with good fuel flow from the filter, I couldn"t get it to self bleed enough to get fuel to the injectors. Even the return line has fuel, but no fuel comes out of the pump when that line is off. The manual says to just crack the lines until the air is out. I did that but still can"t get fuel to the injectors. What is the procedure for bleeding when reinstalling a rebuilt pump? Help!

I usually bleed the pump by hand before installing. It saves wear and tear on the starter motor and batteries. Very easy to do with a hand-held oil squirt-can full of diesel and a big screwdriver to turn the pump.

That being said, that Stanadyne/Roosamaster pump is self bleeding if it was repaired properly (I doubt it was rebuilt).
In my world, "rebuilt" means that all the major parts are replaced or renewed in some way, and that is NOT what is done with those pumps except in very rare circumstances. They get $50 worth of small parts thrown in, major parts uses as-is, and a big repair bill attached.

If the pump is right, and there is air-free fuel available to the inlet, it will bleed out on its own. If there is ANY air in the fuel, it won't.

Interestingly enough I contacted the repair co. and after some conversation they told me to send the pump back for them to take another look at it.

Stay tuned!
