Erratic fuel gauge

My fuel gauge on my 95SW is constantly bouncing all around with the fuel movement in the tank. It swings from empty to full in the matter of seconds. What kind of repair am I looking at?

Thanks Matthew

could be as simple as an electrical connection. That happened to me although that was on a RRC.

It seems to be with fuel movement, or if I'm on a hill of any kind. Would that be a connection or the sending unit?


Thanks Matthew

Mine popped out of gear over the weekend and landed the tank pretty hard on a rock...now it thinks it's full all the time.

Same thing for me or other ideas?

Kevin,

It sounds like the float is just jammed up at the top somehow. I say drop the tank and pull the pump out to see if the float is ok.

Matthew, Is it the stock gauge, or an aftermarket replacement?

Most aftermarket fuel gauges bounce around more than a sugar-fueled 5 year old in one of those inflatable houses. Always found it odd to that every OEM fuel gauge I've ever seen has some kind of dampening to slow it down, and almost no aftermarket gauges do.

Aggie, your issue sounds like a wire popped loose.

I just bought the D90 and it's my first so I'm not sure if it's original or not. Is there somthing I should look for?

Thanks for your help Matthew

I have a used fuel gauge thought it would work in the 97 it did not 95/94 are different. It's yours for shipping if you want to give it a shot. I can always use the defender Karma credits.

That's what I was thinking too...the ground wire probably came loose.

I think there was a bulletin when the 90s first came out about the erratic fuel guage. You might ask the dealer if they can pull up anything on it.

Thanks for all the info, I'm going to give a few tanks of fuel and see how it does. It seems to be improving now that it reached 1/2 of a tank.

Never trusted mine. I go by the odometer. If I hit 185 miles, I will run out at the side of the road. When the tank is full, first 1/4 tank evaporates really fast. Next 1/2 tank really slow (lulls you into a ffalse sense od security) then last 1/4 speeds back up. If I hit the red zone, I have 3 miles to find gas. Oh, and at this point the gauge likes to bounce - just to F@^# with me for letting the tank get empty.
