I have a 2000 sahara. I swear that friggen light is on more than its off. I get all paranoid since the milage is so bad. How may gallons ae left once the light hits?

And is there any way to improve gas milage? Does a hardtop help?

That guage is so inaccurate I wouldn't trust it too much. On mine it can be at 1/8 tank. Then if I shut it off for a couple minutes and then start it again, it won't return to the same reading, it just sits barely above E.

according to my owners manual for a 98 tj the light comes on at around 3 gallons left in the tank which is about 45 miles or so,, i dont think anything changed in the 2 years that would make yours any different,, you can take off you lift- put on smaller wheels and coast down hill and try to get a tow from others as much as possible-- in a jeep that is about the best way to save on gas!! there are other ways like exhauset and air filters and a bunch of other things that you can search for in the forum and find out about

I fill up as soon as the light comes on and I've never put more than 14 gallons in to fill-up. Considering we have 19 gallon tanks, I'm assuming that I have another 4-5 gallons to go once the light goes on.....I've just never been brave enough to push it and see though.

I've only put in I think a max of like 17.5 gallons, that was with the light being on for about 60-80 miles in city though. When I fill up just after the light goes on I have about 6 gallons left.

Early TJ's came with a 19gallon tank but it was listed as a 15 gallon because a breather tube extends down in the tank, limiting how much gas you can fill up with before it shuts the pump off. I had seen a write up once about taking the tank out, removing the sender, and cutting off part of that breather. Cant seem to find it now though.

I know mine goes way before E before running out. It isn't even touching the bottom. I took a Jerry can around one time just to find out. I kept on filling up when I thought I was close to empty and only sticking 16 gal. in.

Just remember, the gas is what cools the feul pump, don't be in a habit of running on 'E' all the time. I fill mine at 1/4 tank.......
