I recently installed the AEV 2" spacer lift, and now my fuel guage is off. When I fill the tank, the needle only goes to about 1/8 less than full, and the low fuel warning light comes on even though I have about 5 gallons left in the tank. Also noticed that when I turn off the ignition, the needle REALLY buries itself now below "E".

Any ideas? Is this something that the ProCal fixes (I have not purchased a ProCal yet). I have been trying to get away without buying the ProcCal, as my speedo is only off by maybe 1 mph with my 285-75-17 KM2's.

Appreciate any thoughts or ideas.......

 

Measure your height and compare sounds like your nit sitting level. ProCal will do nothing.
