fuel gauge

I have a 91 YJ that modified with suspension, shackles the usual. Problem is that my fuel gauge will jump up and down like a mexican jumping bean at idle and while driving. Any one else experience this?

Re: fuel gauge

Your gauge is going bad. I've seen this in a few of the older Chevy trucks that a relative had. The sending unit is ok, but the gauge end should have a damper in it to keep it from moving too fast. If you can take it a apart, a little bearing grease on the pivot will help, otherwise replace the gauge or live with it.

Re: fuel gauge

my gauge does that to it has been that way for three maybe four years it really entertains the passangers though. maybe i should sell tickets so others can laugh at the gas gauge while riding. ha ha ha

no solution for you but good luck maybe some day i will try the grease trick
but for now it will stay as the bouncing banshee

Re: fuel gauge

my gas guage has always done that, probably need to go to an after market guage to fix it?

Re: fuel gauge

those gas guages are actually supposed to move? Mine is perched on the E and doesn't move. I thought they were there for decoration only.

Re: fuel gauge

Can you provide more detail regarding the damper issue and the grease fix ? My 88 Wrangler has had the bouncing needle problem for years. I thought that the sending unit ground was intermittent or else the pickup wire in the sending unit was broken . I was awaiting warm weather to drop the tank to investigate these things. Your comments are intriguing . I would prefer to work on the the gauge , but I do not know what I need to do to fix the Damper issue . Can you clarify this ?

Re: fuel gauge

There is an article in the jeep tech pages on this and helps to trouble shoot the problems. Hope this helps.

Re: fuel gauge

I just learned that 2 folks reported that the fix was to resolder the "G" wire at the dash gauge unit. I will try when the weather is warmer.

Re: fuel gauge

Not necessarily related, but a funny story: My CJ fuel gauge had gone out of commission about 2 months ago. Since it had never really been accurate (empty is actually 1/2 tank) I really didn't miss it. But last week I was up under the rear end working on my driveline, and noticed a ground wire had broken loose.

Hmmm, thought to myself, only three things need ground back here, reverse lights (never worked), brake/turnsignals, and fuel sender. So on a whim I put it back on a ground screw and viola, the next time I got in and cranked it, I had a quasi functional gauge again!!! [img]/wwwthreads_images/icons/laugh.gif[/img]

Re: fuel gauge

Bluesman2a,

Where exactly was that ground wire? My guage is exactly the same, 1/2=Empty. I'd like to try what you did.
