CIH 5230 fuel tank sending unit

crsutton81 · Dec 9, 2021

On a 5230 tractor with the large
fuel tank, I need to remove the
sending unit from the tank. Is it
possible to totally withdraw it from
the tank with the tank still mounted
on the tractor or does the tank have
to be removed to get it out ? I have
the seat and floor plate out of the
way.

I can't remember for sure. I had the tank out of mine, and after removing the wheel, it wasn't too bad of a job. The sending unit hasn't been available for years. If I had known CaseIH/Fiat or whoever it is was going to abandon me, I wished now had I bought a new sending unit back then. Because now my fuel gauge is a stick.

But you can trust the accuracy of a dip stick. Provided of course the person holding said stick isnt a dipstick, lol

Did yours have a filter of some kind on the end of sending unit ? I'm getting an air bleed or lack of fuel on this one from somewhere at the front corner of the cab to into the tank. Everything on engine fuel wise has been rebuilt or replaced. About to pull out what hair I have left. Does this sporadically now.

Have your fuel lines been replaced? They rot out. Mine were already replaced when I got the tractor. The original ones were abandoned behind the tank. When I had the tank out I removed them, and fine tuned the placement of the replacement ones.
There was a serial number break on fuel gauge sender/fuel lift pipe. Early ones had a screen on the bottom end. Later ones did away with the screen and put a little in line filter just before the lift pump to keep debris out of the pump. When I had mine apart I drained and flushed the tank, tore off the in tank screen, and installed the in line one by the lift pump. Then, later on the fuel gauge quit working. I have tried multiple times to get a new sender. No luck.

No wonder it's been giving me trouble. I need to find someone else to check the fuel!

Update.....Did a little jack leg plumbing by dropping a fuel hose into the fill neck of tank then to the fuel lift pump. It ran great. We were able to get it to the shop for permanent repair.I was able to remove the sending unit without having to remove the wheel and take the tank out of the tractor. Had to keep the seat tilted back and finagle it out of the hole, but it can be done. Sure saved a lot of time like this. I removed the fine screen on the end of pickup tube. It looked to possibly be floating up and the flat bottom on it covered the tube inlet hole. Didn't realize that it still had both of the original braided fuel lines on it that connects sending unit to the metal lines under the cab. They will be replaced tomorrow. Hopefully this will fix it.
