    Fuel Gage 1997 SLS

    Hello All:

    I have a 1997 SLS with 36K miles. The fuel gage is not working properly It jumps around frequently and it changes after you turn the car off and then restart it. I moves up to 1/4 either way. I ran outta gas between 1/4 and 1/8 reading. I just ran a full tank with Techtron. No improvement. I guess I'm another of those dummies who hopes for a miracle in a bottle. Besides filling up when it reads 1/4 or watching the trip computer does anyone have any suggestions?

    Thanks:

    Larry

    your fuel level float is probably bad, you have to replace the float which requires dropping the tank

    The problem is not the float, but the electronic portion of the sending unit. It all gets replaced together anyway. I'd suggest replacing the pump as well while you're in there.

    A 1997 requires a total fuel tank drop. Look for a DELPHI, Airtex, UltraPower fuel pump module in www.rockauto.com. The modules come with the pump, ( ?? fuel tank pressure sensor ??), level sender, float/arm, and primary filter - and maybe an upgraded electrical connector pigtail.

    Take the advice to replace the entire unit - you won't want to do this again.

    I have yet to see any "Hope In a Bottle" solve this problem. Like everyone else said, I'm afraid you are in for a tank drop and a level sensor replacement.

    I would agree with Sub. May as well do the whole thing while you are in there. I don't think the price difference is all that great either.

    Thank you everyone..I think I'll just fill it at 1/2 or every 250 miles on the trip computer. I was of course hoping for a cheap and ez fix.

    Thanks:

    Larry
