1973 820. Transfer pump looks rough, but seems to pump well. Cut off solenoid audibly engages with the switch.

Doesn't mean it's holding. Normally closed is how they work. So it's held open while running. So as it gets weak, more shut offs....

Also members Tx Jim and/or thepumpguysc may be able to add more specifics to your question regards the '73 2-cyl 820 injection pump.

At the end of the season last year the tractor would run strong for a while, but then loose power and stall out. It restarts right away, but within a few minutes looses power and stalls out again. It seems to run longer if it has been parked, with a shorter run time after every restart.
There was rust scale in the transfer filter and the diesel had a reddish tinge. Fuel tank was replaced. New fuel looks great. Bleed the fuel lines from the tank to the injection pump until no bubbles a section at a time. There is a new return line off the injectors as the tank is a different style than the original.
I have read that breakdown of the plastic inside the injector pump listed as a common problem with the Roosa master pumps.
Is there anything else to consider before sending it out for a rebuild?
Thanks,
Joe
Ps I can work on posting a video link also

thepumpguysc did a good job on our old FORD pump rebuild. Even sourced some no longer available parts needed.
Tractor is running strong. I recommend you talk to him.

On top of the pump is a checkball return connector..
Remove it and start the engine.. fuel WILL flow out of the open hole so be prepared for that..
It should stay running..
I’d be happy to have a look at it.. just contact me thru this site.

Yup.. sounds like a clogged return connector..
Remove it from the pump..
Start it and see if it continues to run.

I’ll give it another try this weekend. If so does this mean time for a rebuild?
