Reviews for OMIX 17209.04 Fuel Gauge for 72-86 Jeep CJ Series

Fits

This took a lot of time and work to get this working. Fit great within my Speedometer cluster, but I didn't have the gauge as tight as I should have to the cluster - fyi it has to be sort of uncomfortably tight to make it ground out. I also had to add a ground wire from the Speedometer Cluster mount to the dash and ground it to the Battery. This of course was after I had a new sending unit & complete fuel system installed. I had to spend time checking every wire to the tank, multiple times. Just first add a ground and then check the tightness of your gauge to the cluster. It works and I can finally see how much fuel I have - after all these years.

A replacement fuel gauge should be replaced in pair with a new temperature gauge . Both are designed to work on 12 volts . The sending unit for both gauges should be replaced as well to be compatible as well . Worked for me . This gauge worked as wired originally . The temp gauge was pegged . I called OMIX ADA and was told the temp gauge was wired in reverse . I was instructed to jumper from the fuel gauge A position to the temp gauge S position . The temp gauge A position will now take the temp sender wire . This worked . Had to replace the original flat copper voltage regulator jumper with a 14 gauge ( my choice of gauge ) stranded wire and two ring connectors . I suggest installing the gauges in factory wiring configuration first to observe operation first . Make certain to clean all surfaces , gauge to cluster , cluster to dash . Add a ground to cluster mount stud if none present . Make certain that both gauges are mounted correctly and the studs do not touch / ground to cluster housing . Don’t want them to short and burn out . Make absolutely certain the gauges sit comfortable in the cluster . Tighten mounting nuts but not over tight . Follow all reassembly with clean bulb sockets for good grounds as well .

Works great on my 81 CJ7. It's important to make sure that you have your fuel level sensor and ignition 12v wire on the correct posts. As well as having the whole instrument cluster grounded. Otherwise you'll fry this gas gauge quick! My cluster had a ground wire but for added sense of security I ran a wire through the firewall to the battery. The gas gauge has worked fine for several weeks now.

SEEMS OK SO FAR..

Gauge is backwards from original, f and e are transposed.
Gauge barely worked during temporary install, broke while installing in the speedo unit. Do not recommend waste of money.

Don't waste your money. Didn't work.
