Do you have to remove the fuel tank to put in a new fuel level sending unit?

Thanks, Tony

There's two ways . . remove the tank or remove the bed. (tilt it up)

TJE

Thanks man, that's what I needed to know.

Do yourself a favor and remove the bed. I had a fuel leak in the line between tank and frame so I dropped the tank. DON'T DO IT. Remove the bed you will be much less agrivated when you are done.

If you drop the tank empty it as much as you can before you drop it. I dropped mine with a floor jack with no problems. Pulling my bed was not an option due to a special hitch in my bed that is tied to the frame.

Thanks for the tips guys. I have a steel flat bed on the truck so raising the bed is not an option. I dropped the tank as far as the straps would let it go and was able to get it out without taking it all the way down.(It is 3/4 full now) I'm going to go fill the tank up in a few minutes, I'll report back to let you know if it fixed the problem.
Later, Tony

Well guys that didn't fix the problem. It now seems like it could be worse than it was. When I left the house it was just a little more than 3/4 full, it then went to full and before I got to the station it was down to 1/2! I filled it up took 6 gal. It finally moved just a little more than 3/4. Before I fixed it once it got lower than 3/4 it worked fine. Only when you filled it up would tha gauge jump around.Any suggestions?

One ? does the level unit itself need to be turned a paticular direction in the tank? What about the housing that slides down in the tank. It seemed to be spring loaded, was this supposed to move?

Thanks, Tony

There is a arrow like mark on the top of the sending unit housing and it is supposed to go between two hash lines on the tank, if not the sender arm may hit the sides of the tank and not raise or lower completely. The fuel sender is spring loaded to allow it to flex up and down with the plastic tank, hope this helps!

Oh.. now I see U have a 91... the info above may not apply unless you have a plastic tank.... but if I remember correctly the spring loaded sending/pump units were only on a plastic tank so it should still apply.... good luck!

TJE

Yes, I have a plastic tank, so I'd say it applies. I never even noticed an arrow, or hash marks Guess I get to redo it tomorrow

Thanks, Tony

If the construction of the flat allows, CUT A TRAP-DOOR in the flat, above the fuel-tank brain-center.

This way, any future dealings with the fuel tank will be simple.

TJE

Yes, that is a good idea!
