Fuel gauge reading 1/4-1/3 tank too high

Postby wally426ci » Sat Apr 22, 2017 12:06 pm

I am trying to figure out what can make it read accurately (as far as a range is concerned)

Sick of it to the point of possibly using a sight glass drilled in like you see on Choppers....

Simple.
Gauge defective, voltage wrong or resistance wrong, its the (Ohms) law!

It could be the float arm needing adjustment.

Thanks Bill. I reached an epiphany while responding to Buds PM.

I've adjust the float arm with slight imrpovements but now wondering if maybe the internal contact is touching the spring at the wrong location....
