Need some urgent help, kubota diesel

[texbaylea]

You did not give the model of your tractor but this might help. The early small Kubotas did not have a fuel pump. They were gravity fed to the injection pump where there is a third bleed screw. It sounds very much like a problem in the tank or that first hose.

I appreciate all the help, im an idiot when it comes to diesel engines.

The tractor is a kubota g5200. 14hp. I think its around an 89 model. Theres a piece that look like a pump just after the prefilter, it has electric wires running from it.

i would check the tank side first. you can siphon the fuel out then look for blockage either at the bottom of the tank or in the fuel line that goes to the filter.

I got the tank out and check the line from the tank to the fuel pump. Its clear. I think the fuel pump is dead. My question is should it be pumping diesel to the front when the key is in the on position? I unhooked the line at the front of the fuel filter near the engine, turned the key to the on position and nothing came out!

Not a mechanic by any means but the fuel pump? in the picture looks like where the problem was on a grey market excavator. It actually had a filter in it. We were unable to locate a replacement element but cleaned it and cured the problem.

I think what your calling the fuel pump is actually the fuel solenoid. Pull hose off going into it, splice it to the hose going out of it, and see if unit will run.

Im almost positive that parts the fuel pump. I think the solenoid is the black box on top of it. The manual doesnt point it out directly, but does talk about keeping the prefilter clean so the pump doesnt clog up. I held onto it while turning the tractor on and i get no vibration or anything. If the pump is cheap enough ill just replace the whole thing.

can you test the wires for voltage?

Im going to run this afternoon and get a voltmeter and check that first.

The new pump is $77 which isnt too bad.

I had a B-6000 with an electric fuel pump. The only problem I ever had with it was the fuse holder got wet and started to corrode. Pulled the fuse, cleaned it off and I was good to go. Checking voltage at the pump is the best suggestion so far!


Good luck,
