Fuel Gauge Problems, need some help

[Sterling]

Hello guys,

I have dual gas tanks. Here is my situation

Full to the rim, the Right hand tank when selected reads just at about HALF tank. Then it reads going down from there. Reads about the dash after empty at half tank, and really doenst go down farther from there, Ive gone to about 16/20 gallons used, but I dont dare go further to run risk of running a diesel dry.

Now the left tank (drivers side) reads about a half inch past the Full line , but doesnt move at all


I have a feeling the left tank has a ground issue with the sender, and I feel the sender or float is bad on the right.

Am I close? or has someone experienced this before and knows better?

I want to tackle 1 tank at a time, I can atleast drive it with one tank off. But want to have parts ready
