Auto Meter Guages

leegMember

Over the weekend I upgraded my center guages (temp, fuel, oil pressure and changed amp meter to volt meter) to Auto Meter Ulta lite guages. The fuel guage now reads full even though the tank is only 1/4 full. I read that a probable cause of a "full" reading is that the stock sending unit is sending too high a voltage to the guage and that installing a resistor will correct, or partially correct the problem. Has any experienced a similar issue? Any Thoughts on corrective action? I'd prefer not to replace the sender unless that is my only option. Thanks, Lee

does the autometer state what type of sender it should be used with.
(what is the part number as the sender range is provided on their web site)

the original sender is 0ohms full / 200ohms empty

Apparently the AutoMeter fuel gauge is compatible with GM senders with 0 ohm empty/ 90 ohm full. Looks like I have three options. Replace the gauge with AutoMeter Ultra Lite # 4310 which is programmable from 0-280 ohms but is twice the price. Replace it with a 240 ohm empty/33 ohm full AutoMeter gauge and add a 40 ohm resistor or find a new sending unit that is compatible with the gauge I have.

You could get a gauge calibrator that allows you to mate any gauge to any sender.

You have a 4th option that is a bit more technical, but a brilliant solution: Meter Match. There are a couple of threads to follow here:

during my search of autometer, I saw where they would change/calibrate to your specified sender for $25.

But I think the meter match would be the best option as it allows multiple slope calibration to match the varying volume of the tank with level

Meter Match sounds like a good solution.

Goodroc posted on Jan 29, 2016 "Metermatch does not need to interpolate levels between full and empty. You can set an indication on your Gauge at 2 more intermidient levels. The Metermatch will then only have to interpolate in the range between any of the settings you made during the calibration."

I just order one from the TechnoVersions LLC website. $51 including shipping. Certainly worth the experiment. Thanks for all the comments. I'll post an update once I get it installed and calibrated.
