Fuel Gauge Calibration

Cheers,

I just calibrated my fuel gauge recently. I've driven about 130 miles on the current tank and my fuel gauge still reads full. The fuel sending unit provided by Kirkham is really a super piece, very nicely made; however, because of the angle of the unit inside the fuel tank, the gauge will not operate in a linear fashion.

Ron,

thanks as always for reminding us of the KISS principle.

Of course, that would mean that I have to calibrate my odometer too...

u going to the roundup?

There are a few factors that can make the sender non-linear, the sending unit itself, odd shaped tank, and of course position. If it leans heavily in one state a bridge resistor circuit can level it out somewhat.

If the sender had a float arm (sounds like thats not the case here), you could also use "S" bends on the arm.

Of course there's always the tried and true "graduated broomstick" method.
