Fuel Guage Sending unit

I just tried replacing the fuel guage sending unit in the fuel tank of my 83 cj7. Dropped the tank put in the new unit and replaced some of the rubber fuel lines. I started the jeep up while the tank was still suspended and it ran fine. I bolted the tank back onto the frame started it up again and it died after running for a minute or so. What could have gone wrong?

Re: Fuel Guage Sending unit

I dont think any of the lines are pinched, I dropped the tank again and put the old unit back in because the new one wasnt even the right unit for my tank. But it still wont start.

I'd change the fuel filter next.
While it's out you could turn the starter to see if it's pumping fuel. Take care not to spill fuel.

If you remove the left rear wheel you can look between the frame and body and see the hoses.

Re: Fuel Guage Sending unit



You aren't one of those guys that put the wrong pickup in the tank, have it seated firmly against the bottom of the tank so it can't suck up anything? (yup, I did that...)
You know, like when Ford decided to make 42 kinds of in tank pumps and pickups that all look alike, but won't interchange...

Have your lines connected correctly?
Sucking air into an intake line can be maddening to find!
(Ask me how I know that!... But duck when the answer comes!)

Re: Fuel Guage Sending unit

Yeah, I put the wrong unit into the tank, figured it would work until I could get the right one. All my lines are hooked up correctly, I followed them and refollowed them around the jeep to make sure. And then I put the old but correct unit back in.
Still cant get it to start. I kind of put the problem off for later since Ive got two other projects going on right now. But if you've got any ideas I could sure use em. Thanks.
