Re: help me decide if i should buy a fuel tank sending unit
Had the same problem with mine.
I 1st went to the aluminum wires in the sub-harness, that reside near the left tail light. Right then and there, the wires accidentally pulled away from the nylon connector. Gave me the chance to test both the gauge and the float. Not the float.
Then I re-connected the aluminum wires directly to the copper wires in the main harness, thereby eliminating the nylon plug.
Next, pulled the gauge. Reinserted it, pulled it, etc., several times. Problem solved. Oxidation was the problem.
Side note:Aluminum wires were a bad engineering idea, regardless of whether or not they were actually at fault.

i found this at autometer.com. doesnt any one have any more speific info about are cars, regrading this?
Why does my fuel level gauge bounce around when I am driving?
If your fuel level gauge stays still when the car is still, the problem is due to sloshing fuel in the tank. When the vehicle is in motion, fuel is allowed to move back and forth and move, or “slosh” around. Many late model tanks have internal baffling and some fuel cells use a foam insert that help keep fuel from moving around too much. When the fuel is moving around, it is moving the float up and down on the sender, which causes the gauge to respond by moving back and forth. Some OEM’s have also used what is called “anti-slosh modules” to battle this problem in production vehicles. Unfortunately, we know of no after market anti-slosh module to operate with an after market fuel level gauge. Some amount of slosh or movement is normal with a non-baffled or a non-foam filled tank.
