    Few weeks ago my fuel gauge went to full when I only had 1/4 tank, then it went to empty,then half. Now its just staying at half, no matter what, even when turning car off and on. So could it be the gauge or sending unit?

    Possibly a bad anti slosh module in the instrument cluster. This is how to bypass it on a Taurus and is probably the same or similar on an Escort.

    I replaced the gauge in my old 97 tracer to fix the problem.

    Was it the gauge or anti slosh module? If it was the anti slosh module and you bypassed it, you'll likely see a variation in the gas gauge reading during hard acceleration, hard braking, sharp curves, turns and while going up or down steep hills.

    It was the anti slosh module I bypassed it. I dont care about the variation just as long as my gauge works lol

    That is cool to know we can bypass the antislosh module on ours too. I will probably be doing this soon as well. I never minded the old days of cars when the fuel gauges bounced around a little. I liked that you were always being shown the level instantaneously. If I start mine on a downward hill, it will usually read on e for at least 4-5 minutes before it starts working its way up to where the level truly is and that is just plain annoying.

    I just wanted to know what the problem was in case the question ever came up again about a stuck/non working gauge. Also I was just making you aware in case you didn't know that there would likely be gauge variances under certain conditions. If push comes to shove and you want a gauge that doesn't fluctuate, you can always get another anti slosh module at a junk yard, probably wouldn't cost more than a few dollars. Glad I was able to help.

    Apologies for resurrecting an old thread. The fuel gauge on my 91LX stopped showing anything more than a vague 2/3rds of a tank. It was okay when the tank didnt leak and we could just fill the tank and reset the odometer. But now the tank leaks when filled beyond about 7 gallons - and the smell makes my wife ill.
    I tried plugging in a new fuel sender unit at the harness under the seat; but it worked just the same.
    The anti-slosh module showed signs of a roasted area under a resistor; so now I think I will bypass it.

    Also will be dropping the tank to replace that 9/16" vapor hose feeding back into the fuel filller neck, as well as the larger rubber tube; the KFL-22 item.

    I had this happen in a first gen after changed the full pump and sending unit.
    I changed the gauge and it still was happening. One day I was driving like mad on a back road and hit a nice bump or two and it went away.

    Denisond, there are two grommets on the top of the fuel tank for vapour venting. I got them from my local Ford dealer. They took a few days, so you might wish to order them ahead of time.

    It's great to be able to fill the tank completely now without it leaking, unfortunately I don't have a working fuel sender.

    If and when I fix the fuel sender I will do a how to article about it.

    I saw on ebay a fuel sender, just the sender, not the pump. It looked to be an Escort type of sender, and was at least with a Ford part number. It was $19.

    I'll look that up. So far as I know, most Fords of the era used the same sender, but with a different arm/float attached.

    On mine, the thin brass wiper dissolved away, so I made a new one. It too dissolved away. Crappy old fuel.

    My search was inconclusive on ebay, but I did find one on Amazon. Unfortunately a lot of suppliers will only sell a complete unit with sender, fuel pump hanger and float & arm.
    All that is needed is the actual sender, since the other used parts are generally reusable.
    Sending units are the same resistance across the board on Ford vehicles starting in 1987.

    This one's for an Exploder, but it's the cheapest and it should be possible to remove just the sender unit and discard the rest.
    It's annoying having to buy a lot of stuff that's not needed, and presumably the sending unit itself must only be worth a buck or two since this whole rig is only fifteen dollars.

    I'd buy that! Fuel pumps if on sale are cheap. Meaning you can now assemble your own unit for less than buying a whole one! Only questionable part is matching fuel screen to the pump inlet. My screen floats around my tank so it sometimes blocks my float so my meter can be off. I just fuel up before I go 200 miles.
    Getting that O ring to set right when you try to lock the top is such a chore or I'd have done swap out my screen by now.

    Yeah, the O-ring (actually a square cut ring) can be tough. Sometimes it has shrunk, and sometimes it has swollen.
    I bought a cheap flea market long reach, small screwdriver and bent the end to 90 degrees to produce about an eighth inch dogleg. When installing the fuel pump hanger assembly I use the tool to insure that the ring is pushed into place.
    I also put never seize on the locking ring to ease removal next time.
