1975 JD 830 Diesel, leaking Inj Pump

About a year ago, a small leak (a drop a minute) developed on my injector pump, it has steadily gotten worse. A fellow JD owner said it was due to changes in fuel, to ultra low sulphur. Dealer says they no longer work on them, they send them off. Is it worth trying to repair, and if not, does anyone sell rebuilt pumps?
 
Where's it leaking... past the throttle or "kill" shaft?

That can even be repaired by replacing an "O" ring without even removing the IP.

ANY competent diesel shop shouold be able to go through the pump for you.
 
Just buy a $12 seal kit and fix it. Send it to a shop and they will put $25 in new parts into it, calibrate it and call it "rebuilt", and charge you $600-$800.

830 came with a Stanadyne(Roosamaster), CAV, or Rotodiesel pump. Which one do you have? The Standadyne is the original design and the others bought license to copy.
 
It's not due to new diesel. Had ours fixed twice on the 820 (3 cyl). 1970 model. Just happens with use/hours.
 
I had a leaking injection pump on my JD 2940. I took the cover off and replaced the tiny o-rings, put on a new gasket and it quit leaking. Roy

Do you have that injection pump parts supplier address handy? I lost the info from the last time you told me when the kids crashed the computer last year.
