    Posted: 03 Jul 2018 at 8:29pm
I just bought a 1979 Allis 5020 FWD tractor. It runs great and is in wonderful shape. However, I noticed an intact stripped wire dangling from a part on the right side of the tractor (as one is seated) it is red and the other black wire is grounded to the block. This part is on the other side from the fuel filter and has a hose running to it. The part in question looks as if it could be unbolted and emptied or cleaned out. This mysterious part maybe some type of additional fuel filter or fuel pump. What I need to know is what exactly is the part, where should the stripped red wire be connected to, and does it indeed need to be serviced. Please, any help will be appreciated. Big smileuploads/18664/wire1.JPG

The picture is of an electric fuel pump. It is not original to the tractor

Do I need to connect the red wire to the fuse block or something? Have any idea why someone would have put this on the tractor?

I can only think of two reasons to add an electric fuel pump. The first one would be to transfer fuel out of the fuel tank to a different fuel tank of a different tractor or mower. That would be unlikely although has been done on larger tractors. The second and most likely would be to force fuel to the injectors to remove the air from the lines to get it started after running out of fuel. You run it out of fuel and it is fun getting the air out of the filter and injector lines. When I bought mine the dealer said, (DO NOT RUN IT OUT OF FUEL) The first time I ran it out of fuel I totally understood why!

Thank you for the explanation. I did not understand why someone would add that unit. I did one time run out of fuel on another 5020, and it was not fun to start it. I had to bleed the fuel from a small bolt to let the air out.  So I always make sure I have plenty of fuel in the tank. I guess that I will just heat shrink the end of the wire and leave well enough alone. The tractor runs great as is.  Thanks so much for the information.Smile

With any diesel or gas for that matter it pays to never let the fuel tank get below 1/2 full
doesn't cost anymore to keep a full tank than a near empty and you have far fewer problems with a full tank.

Ya, I understand that but when you trying to get a field done and you only have a few more rounds to finish, and Ooops.
