Another fuel sending unit question


Recommended Posts

My truck, since new, has had an ongoing fuel gauge issue. Warranty replaced it 3-4 times. Warranty ran out years ago, but occasionally it will freeze at full. The second to last time it got stuck at full, it started registering fuel level after driving on some bumpy, rutty forest roads. It froze again at full just before the new year, so yesterday, I took it off road to try some bumps and sure enough, it started working again. Anyone have any ideas what would cause it to stick and then get jarred loose by rough roads? Thanks.

I just had my fuel module out and can see what Dripley is talking about. You want to turn it a little counter clockwise.Also check the wires connection on the top of the tank. Mine doesn't click in or lock anymore so I had to zip tie it.
