    Low Fuel Light

    is there an adjustment for this? I would like it to come on before it goes below the E. At that point you could be in trouble

    It's supposed to come on when there's 2 gallons left. As far as changing that, no idea.

      Well, if two gallons left is just to the wrong side of E than it works perfectly.

      Need to see if it is adjustable

            Mine, when its working right, kicks on at 1/4 tank. I have a bad ground somewhere tho because it randomly lights up. Unplugging and re-connecting the module seemed to help some, so its probably dirty connections. Module should be located under the driver's side of the dash towards the center. Its on that flat "plate" thing next to the climate controls and all. Its pretty easy to get at really, and its stamped "low fuel indicator" or something obvious right on the plastic case for it.

              My book claims it to be 3 gallons when the light comes on, dunno. My gauge is screwed up, but when that light comes on I know exactly what I got left and I hightail it come lol

                will try unplugging that module, it works reliably, just wish it would come on sooner

                  Dunno, my friggin civilian fuel gauges would go 1/4 BELOW E before I'd run out of gas. The police one I have in the wagon, when it's on E it's OUT....

                  As for the light, mine usually came on a tad less than 1/8 tank...

                    I think my sending unit is kinda screwed up because my light usually comes on sometimes at a dead on a half of tank or dead on at a quarter tank left. It only happens when its really cold out though when you start it up, most of the time its when its on E.

                      Mine did that, then I unplugged and re-connected the module and it stopped acting stupid for the most part. It acts up sometimes but I suspect a bad ground strap on the tank.

                        mine comes on when it feels like it around e, look under the gas tank where all the crap plugs in, my old chevy had a small float sender just for the light, bend the rod and magically the light comes on sooner, or just watch the damn gauge and know what you have for gas!!!

                          Ford doesn't use a seperate float for the warning light. It has a brain under the dash that ties into the gas guage.

                            my friend is so ghetto, on his 67 chevy C20 he uses a long, rusty ass rod that he dips down the filler neck to check the fuel level. Its not a fucking model t lol...

                              Not that it probably matters, but that rust on the rod can't be doing the fuel system any good.
