I've got 3 RX3's, and both register empty.

The fuel level sending units were pulled and plugged back into the harness, and raising the float arm registers fuel level.

Put them back in, filled up the tanks...and a flashlight shows neither float rises with the fuel level. We can raise the lever with a coathanger and the fuel level rises on the gauge.

WTF?

We took the fuel sender unit out to see if somehow the float itself has been compromised and it's not. There seems to be resistance in how the arm swings.

We cleaned the pivot and put it in a bucket of water (different density than gasoline, heavier)

Reinstalled, it still doesn't rise properly, but at least registers: one bar with a full tank, but still not floating to the top. Shaking the tank, sloshing fuel around shows some gauge response and then returned to no bars.

Any thoughts? Am I looking at a new sending unit?
