Sending unit help
I thought my sending unit was bad so dropped my tank and pulled the unit. Testing it out of the tank it works perfect. I put it back in the tank that is about half full and it is reading a crazy # at first then drops to 0...why?

Re: Sending unit help
If you pull the brown wire off of the fuse panel where it says FUEL, the gauge should go past full to the three o'clock reading . If you pull the brown wire off at the sending unit and touch it to a good ground then the gauge should read empty. The fuel tank completes the circuit back to the battery for the negative side and it must be grounded to the frame and the sending unit flange must be grounded to the tank.

Re: Sending unit help
Ive done all of those things. New wiring harness from aaw. Even tried new fuel level gauge. I just dont get why it reads fine untul in the tank then acts like its grounding itself out maybe?

Re: Sending unit help
Well just had to stop and think about the possibilities, turns out my brand new sending unit had a pinhole in the float so it filled with gas instead of rising

Re: Sending unit help
Same thing happened to me. Good work finding that. Took me a while as well.
