JimB Posted November 18, 2022 Share Posted November 18, 2022 Would anyone happen to have a blue face fuel gauge for sale? Small lower left. Link to comment Share on other sites More sharing options...
eaglescout526 Posted November 18, 2022 Share Posted November 18, 2022 That’s a hard one to come by. Which year range? 84-86 or 87-90? i might have some 84-86 parts but not 87-90. Link to comment Share on other sites More sharing options...
JimB Posted November 18, 2022 Author Share Posted November 18, 2022 The cluster is early 87. Prior to having the ballast resistor for the fuel pump. Also the relays are in a different order. Wonder if a 86 would work. Link to comment Share on other sites More sharing options...
JimB Posted November 18, 2022 Author Share Posted November 18, 2022 I have a qauge in there now but it has the red. So I put a Azzy's cover it. Just me being anal. Link to comment Share on other sites More sharing options...
eaglescout526 Posted November 18, 2022 Share Posted November 18, 2022 84-86 won’t work as it uses threaded prongs and that slid into some clips in the back of the cluster. Later style uses screws. I might have to do a FYI on Renix clusters. That’s why I asked. So if you have a red face gauge then you’ll need a fuel gauge that screws into the cluster. And those blue ones are rare as the full blue cluster was used in 87 to early 88 only before the new style showed up. Link to comment Share on other sites More sharing options...
jpnjake Posted November 18, 2022 Share Posted November 18, 2022 Could you use the black 88-90 gauge and swap the faceplate? Link to comment Share on other sites More sharing options...
JimB Posted November 18, 2022 Author Share Posted November 18, 2022 If I could get the needle off without damaging the gauge. I could swap with the one I have. Not sure if I should try or not. Link to comment Share on other sites More sharing options...

Not sure if I should try or not. If you’re going to do this, pull an HO cluster or something to practice on just to get a feel. I pulled speedo needles off with my hand just fine with no issues. But these gauges are smaller than a speedo but same concept. Link to comment Share on other sites More sharing options...

Also smart thinking here to fix a rare variant of the Renix gauge. I’d still be cautious to try this myself but a great thought. Link to comment Share on other sites More sharing options...

I Agree with Eagle Scout, from what I’ve experienced the smaller ones don’t pop off as easily as the larger ones. I attempted to remove one once but I stopped fearing of breaking it. Also you can test on more than just the fuel gauge, all the other small ones should come off the same Link to comment Share on other sites More sharing options...

Thank you, I considered trying this on my 87 gauge pack for my Comanche, but just went to the black one Link to comment Share on other sites More sharing options...
JimB Posted November 19, 2022 Author Share Posted November 19, 2022 Well I broke it. Applying steady pressure pulling on needle the metal pin connecting needle to gauge broke. Not going to give up on it. Going to find a new gauge and try again then swap face plate. Anyone have any old fuel gauges laying around they want to sell? Also, any ideas why my 23-gallon tank only holds 16 gallons? A little history, the year was 1999 = I had a 1986 longed 4cylinder, 4 speed, 2wd, base model Comanche. Wanted to buy a Grand Cherokee. Went to trade in my 1987 Cherokee Laredo Mint perfect. Dealer offered $1000 I laughed and started walking out. I kept the Cherokee, and he knocked $500 off the GC. So, I took everything off of the Cherokee and moved over to the Comanche. This was before I was a member here. So, everything was Trial and error. Modified firewall, radiator support, AC system, Dash, Power windows, locks, Mirrors. (Remember 86 did not come with 4.0) So I retired last year, brought the Comanche into garage and stripped the wiring (removed all duct tape and crimps resoldered and heat shrunk, removed all pins from connectors cleaned, Ox-Garded, Deleted C101 connector completely. Did all Cruisers tips. Put everything back together drove to gas station filled tank, registered full (F). Drove around low fuel light came on. Gauge read between 1/4 and 1/2. Ran out of gas. Believe it or not first time in my life. Limped home. Fuel pressure gauge was all over the place. Replaced fuel pump. Before I put everything back in tank, I tested gauge. Empty was between 1/4 and 1/2, full was needle pointing straight to the right. Way over full. Removed cluster. Removed screws holding gauge. Cleaned copper added Ox-Gard reinstalled screws. Top screw kept going round and round and would not tighten. Well, it obviously tore the hair thin wire loose and caused gauge issue. This explains why last fill showed full and not over full. And why I ran out of gas at 1/4-1/2 mark. So went to gas station, filled 5 gallon can, poured into truck. Drove to gas station. Would only take 11 gallons. Gauge reads a little over half tank. I tested float before putting back in tank. So, vent tube in tank is too low shutting off pump or I need to give up on Jeep and start writing novels.

eaglescout526 Posted November 20, 2022 Share Posted November 20, 2022 What if you removed the screws and used the face plate to assist with removing the needle? Link to comment Share on other sites More sharing options...
