1997 SCANIA K93 - Fuel gauge telling lies

Post by solotech »

Our bus tells lies. :-( When it's got 100L-200L, or so, it says it's half full. (315L tank)
A while later, it says it's got 1/3-2/3 of a tank.
Removed the gauge and found the 220 ohm resistor was a bit high and suspected that it maybe breaking down, under voltage. Replaced with a new 220 ohm. Still no go. Now, the gauge sits at empty. No movement at all.

Has anyone had any experience with pulling the sender unit out, or replacing the gauge? Or, does anyone know if the sender is 0-180 ohms?
She's a b!tch to get under and on top of the tank.
