I would try and repair it first. If you take it out and grab a multi-meter, you can test the resistance across the sweep and reference to the service manual

I would try and repair it first. If you take it out and grab a multi-meter, you can test the resistance across the sweep and reference to the service manual specifications. You may find that just slightly bending the wiper arm to add a little tension to it can get a better reading. Look for dead spots or spots that don't follow the linear resistance sweep.

Also consider there is another sensor on the driver side of the tank. They are wired in series to the gauge.

ALSO, make sure the in-tank siphon hose slack isn't interfering with the float arm travel.

Attached a piece of the service manual for you.

I would start with, fill your tank again... then use the meter to test both level sensors to see which one isnt reading full. You can do this by just unplugging both of them and touching the contacts shown in the attachment. You dont even have to open the tank at this point.

This will at least show you which of the 2 sensors is not indicating full.

Then once you know which one it is, you want to burn off at least a half tank, then remove that sensor and test it on the bench to see why its not reading full.

... pulling the Fluke out next weekend. Should be interesting.

Somehow I end up seeing myself just solving it with "Trial and Error" method.
