fuel guage going crazy!
out of nowhere, pulling out of AutoZone of all places, i noticed my gas guage was fluctuating back and forth. I just filled up my tank on Saturday, and had not been driving, so Im not sure whats going on. Sending unit? Everything else on the instrument panel apprears fine and in normal working order. Any ideas?
thanks in advance!

ya, there's a fuse in the kick panel that says "gauges". Gauge fuse is in tact, as well as all others, at least the ones easy to get to. Gonna investigate further tomorrow, looks like rain in 10 minutes.
thanks again!

yup mine did that right before it went out too, finally quit on me about a month ago. Drives me nuts, if yours is the one without the low level light (2 wire) then it's a dealer only part, however, if you have the low level light (3 wire) one you should be able to find an aftermarket one. I wish someone would just tell me whether or not the 3 wire one will work on a factory 2 wire truck without hooking up the third wire.

maybe its worth a shot? if you can look at the wiring diagram and see where and what that 3rd wire goes to, and if your truck even has the part it connects to, whatever it is.
Or check continuity ??

I know what the third wire is for, its the signal wire for the low level warning light. But no conformation if the float position vs resistance were the same and the level would be correct on the gauge if a 3 wire was used in the place of a 2 wire.
P.S. I doubt this is the case with you, but on my 87 there was also different size tanks that took different sending units. there was both a 17 and 19 gallon tank option. Not sure on yours though.

ok so all fuses are good. when looking around for a sending unit, some guys say i just need a float. other guys say i need a fuel pump. other guys say i need a sending unit. If anyone on this forum is not guessing, id appreciate direction.

what does a fuel pump have to do with fuel tank level? And to my knowledge there is no such thing as just getting a float for the sending unit, it's all one piece.
