Hi all -

New member here. I recently brought home my dad?s 1964 Ford 4000 4-cyl diesel tractor. It had been parked for about 3 years because he said the injector pump needed to be rebuilt. I got that done and when cleaning and inspecting the fuel tank and fittings, noticed that the diesel return tube (that long upright tube that feed from the bottom) was broken off. That could also be a source of fuel getting into the crankcase, based on some things I?ve read.

Anyway, I?m having a tough time locating that particular part. We have 3 others (MF, Kubota, Ford 5000) that returns this fuel to the top of the tank...

Anybody ever run into this problem and decided to modify the return to go in topside? Just curious of opinions.
 
Forgot to mention I also pressure tested the leak off pipe under the valve cover that delivers the excess fuel from the injectors to said return line. It checked out ok.
 
Yes, I have modified and returned to the top of the tank. the standpipe you are talking about is for the return from under the valve cover only. The return from the injector pump feeds to the bottom of the tank and does not use the standpipe. You can repair your fitting/standpipe if uou desire, or it is not necessary to have the standpipe as long as you have no leaks under the valve cover.
 

Yes, I have run into this problem. I drilled the tee out to accommodate the riser and epoxied it in place.
 
Thanks for the comment. Can one obtain a plug for the spot where the return line goes? Or how did you handle that?
