1969 1020 diesel fuel in oil

[Nsewell]

Yesterday I was replacing sweeps on cultivator and I noticed oil dripping from transmission housing I couldn't find the leak. I checked dipstick today and it is way to 2" higher today than yesterday and is diluted with diesel fuel. Any suggestions on where it's coming from?

Just to be certain, engine or transmission is over full on dipstick ?

Your mechanical fuel pump [ side of motor, works off the cam ] has probably failed. They don't cost that much. Get them on Ebay....

You should be able to get a fuel pump from NAPA or other auto parts store for about $40. That is the likely culprit as Jerry mentioned above.

Ditto on probably failed diaphragm in transfer pump.

I am going to replace it in the next day or two. Thank yall very much.

The transfer pump is okay. I pulled the pump back from the block with the lines still attached and pumped it and no leaks. I think now it is the injector pump seal. I took it to mechanic today.

It was the injector pump seal
