onlyinajeep726 Posted June 28, 2013 Share Posted June 28, 2013 Going from "E" on the gauge isn't reliable enough to determine a true empty tank. You'll always have some in the tank when filling up, even from "E". 6 gallons worth? That I don't know for sure. I've heard multiple times that the low fuel light comes on when you have ~2 gallons left. If I'm not mistaken, it says that in the owner's manual also.

ParadiseMJ Posted June 29, 2013 Share Posted June 29, 2013 I can attest personally...and ONLY in my MJ, that when the light goes on telling me I'm almost out of gas, I still have almost 4 gallons in the tank. My XJ only has ~ 2.5 gallons in the tank when the light goes on. Basically the same sending unit (basically), but it's placed in a different spot on the tank (and on the truck) and varies depending on the way it's parked (up or down, right slope, left slope or level). Not an exact science. Link to comment Share on other sites More sharing options...

Not an exact science. that is true, all i know is that my light don't come on, i don't know if the bulb is burnt or if i don't get the light cause i don't have a computer, Redwolf Link to comment Share on other sites More sharing options...
