DBG Injector pump help

Is there a place to find a new transfer pump rotor for a roosa master dbg injector pump?

What is the complete pump number? Very early pumps had separate left or right hand threaded blade drive like CAV DPA pumps. Late D series use one piece rotor/blade drive.

I believe that mine is removable. Problem is I cannot get it loose with everything I have tried. I need a backup in case it breaks during removal. I am trying to restore the tractor.

That one is NOT removable, it's the EARLY pump that has no delivery valve like the 8AJ pump I have on the test stand now. Yours has a one piece rotor/vane drive like later pumps have, just no delivery valve..

So there are no internal seal that would need to be replaced? I was rebuilding due to no pressure going to injectors.
