Hi guys, recently on my 2001 G400 my fuel gauge does not go over the first quarter on full tank?

I have checked the sender unit- no gunk very little corrosion which i try to clean as much as i could.

There seems to be no more than. 1 volt coming from the wires.

Should there be a full 12volts on ghe Plus wire?

Has anyone had or know where else i can look for the problem?


Thanks gooch
