Fuel tank sending unit.

My fuel gauge with the sending unit now is showing ¼ when the tank is close to full. It looks like the sending unit is in upside down, but it will only go in one way. Should the wire stud be on the driver side or the passenger side? Or maybe one of you guys have a part # I can compare it too.

Is it a factory original sending unit or an aftermarket one? Typically, aftermarket re pop’s are junk and will read wrong. I have heard that Vans are now doing an accurate repop, but have not tried them myself.

Mine reads the exact same thing. Original rebuilt gauge and a newer sender. I’ll be looking in to the Vans sender too haha.

What really sucks is that the sending unit works when I test it outside the tank, it will bring the gauge up to 3/4. It seems like its upside down when its installed, but it only goes in one way.

I've heard that you can bend the float down, as a possible improvement.
Aftermarket sending units, usually are "cheap China ****".
You may find a place that sells better China ****, but who's got the time to "F" with that .
Worse (for me ) was the thin-*** locking rings, that they send with them. At least "Detroit Muscle" can help with that.

I usually have some NOS rings if needed. The repop are to thin.

I tried to bend the one that was in the car. It does test ok outside the tank, if I hold it the opposite way it belongs in the tank, then the gauge will go to 3/4. I'm thinking it's just the wrong sending unit the guy before me put in.

People on here have said it’s something to do with the signal from the sender. Linear vs nonlinear. Mine tests fine too, it’s just something about how they talk together.
