Well it's installed now, tank has about half full of fuel I checked by hand before installing to see if it was on the ball park and it says just over half so it's close probably, lines are kinda relaxed now I moved them around the fram some and they seem alright now, old one was held in with a bunch of blue silicon in think maye the old one was wrong maybe? Or new one is aftermarket and just a little different? . It seems to be sitting correctly in my tank, and reading at least close but I won't know until I top off tank and see gallons it takes or if I run out of fuel randomly and tank reads not empty? But I feel it's pretty close. Maybe e and f are 22-145 but I've always notices guages will go just below E and just above F so maybe that accounts for when guage it maxed out at either end of the fuel tank? With my 16-170 ohm readings? Or when it's in the tank the tank physically won't let the float hit these max marks I can hit while the floats not in then tank?
