Hey guys. I just have a random question.
I filled the ZJ up today after the fuel light came on. My mini overhead console said I had about 20 miles till empty. I filled to until it clicked and that was at 18.4 gallons. Now I have the build sheet from Chrysler which says 23 gallon tank. Correct me if I am wrong but that doesn't seem right, 4.5 gallons for 20 miles? Can anyone shed some light on this for me?
I also use a scangauge 2 and that showed I was at 18 or so gallons used. So, why would my fuel light come on so soon and my dte show an incorrect mileage? My scangauge seems much more accurate then computer in the car, even though its plunged into the obd2 port.
Any advice helps.
Side note, my mini console doesn't reflect any accurate information for an unknown reason. I did however think that the dte would be pretty close.
The most I've ever been able to pump into mine was 20 gal, and that was needle pegged on e. I love that feature of making me think I'm low. I'm a college kid and its nice to know I've still got enough to get me to town if something happens and I'm broke.
On a side note, I ran my chevy out of gas once. A week later, a new fuel pump was required. So ill never run my zj on its reserve unless its an emergency. May not be related but I'm not chancing it.

Planned: Homemade Spare tire carrier, double shear front track bar, 4 adjustable rear control arms, New Rims and 33" Wrangler MT/Rs or BFG M/T KO's w/ LOTS of trimming.
Believe the fuel tanks are the same size for both the 4.0 & V-8's since the parts list goes by year/body style rather than engine size. On my 96 4.0 the gal size isn't given for the tank (#52100058, Fed), nor is it on my build sheet, but think it's 20.2 gals. May be the same for the 94-95 ZJ fuel tanks (#52127523, Fed)?
To prevent you from running out of gas. Ive ran mine for about 40miles after my dte said zero before. I use it as a guide, but don't really use it as a for sure thing. Just to get an idea.
Just a fail safe, dumby proof type thing to prevent you from running completely out of gas.
The only time I've ever ran mine out of gas was a few days ago. Gauge showed a hair under 1/8, dte was at 31 and my fuel light never came on. Thinking that was a fluke though since I've ran it down lower than that and had the fuel light come on while I was heading to fill up
