Fuel sending Unit problem

[Rodd]

Some of you may remember my last thread when my fsu went bad. The new fsu was semi accurate until about 3 weeks ago. It is now stuck on E. I got the fsu from tanks-to-pans the same fsu Tim has. Any thought on where I need to look before dropping the tank?

Any thoughts??????

All I can think of would be the ground and the connection, but I,m sure that has already been looked at. Leo

x2.. Recheck the grounds. Same thing happened to my 67 camaro. Pu in a new FSU and it worked good for a while and the stopped woking, it was the ground.

I will check the grounds. The only thing that makes me question the grounds is usually multiple components use the same grounds. I should have something else acting up as well if it is the ground. Just a thought. I think there are only 7 grounds iirc.

My camaro had a ground specific for the FSU. Can't vouche for the newer stuff.

There's a ground down by the the fuel fill some where.......if I remember correctly.
Just a thought.

Thanks! I have been thinking about checking that one 1st. It is connected to the fill tube. I wasn't sure if it was a ground or not since there is really no electrical to it.

It works now then?

It might be a ground more for static electricity, but can't hurt to check.

The one on the fill tube is a static ground. The FSU ground is on top of the frame rail beside the tank.
