Damn guys. Mine is pretty accurate. I still have about 2 gallons once the light comes on.
you guys do know that the newer modules keep the pump constantly submersed in fuel right? Hence the big white module, dual screen and check valve in the bottom. Fuel level doesnt really matter unless you drive something old enuff to use the metal hanger, which no 3rd gen j car had.
If mine gets to around 1/8 of a tank, I better have a gas station in sight because it's already drifting. I don't let mine get below 1/4 tank or it has a LOT of trouble starting. I've had the light come on ONE time, and about 5seconds later it was sputtering and died. So not very accurate gauge here.
