Fuel tank sender

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

Re: Fuel tank sender
Did you remove the alloy cover of the sender ? The float can get trapped by diesel gunk

Only familiar with my early 463, but on that if you earth the feed the gauge will read full?

When you say cylinder removed, you did mean you took tube off exposing the float?

Hi thanks for getting back to me! Yes the round cylinder thing i removed. I cleaned all the contacts inside them not a lot of gunk at all. Going to try the fuel pump relay next, maybe theres a bad curcuit in it possibly hence why theres no voltage at the wires ontop of the sender unit.
Will keep you posted
