Fuel Gauge Problem
I recently ran out of fuel whilst the gauge was showing 1/4 full. Pumped the tank out today in preparation to remove it and check the sender and to do the Hutch mod. There was only 5 gallons in the tank but it was showing between 1/4 & 1/2 full.
Can anyone tell me what resistance there should be across the sender unit.
Mine has 75 ohms at empty and about 220 ohms at full, and the transition from empty to full appears to be at a constant rate.
Are there any other checks I can do? I am reluctant to re-fit the tank if there is any doubt about the sender. [The simple thing to do would be to fit a new sender, but parts like that don't come easy down in Aus].
