Fuel Gage question

Manual for my 97 XJ says I have a 20 gallon fuel tank. Yesterday I put in 21 1/2 gallons on a empty tank. I'm now assuming that I have a 22 gallon tank. I have the standard fuel gage (no low fuel lamp). This gage has the "shaded" area next to the E mark. Twice I've gone past that mark and took the needle farther than I thought I could. Bottom line, I guess I shouldn't really mess around and let it get that low, but I am curious on the size of the tank and how much gas is in the tank when in the shaded area. (on my honda that I used to have I knew exactly WHEN the tank was almost empty.

Makes me wonder if that gas pump is calibrated, or if they're gouging people on every fill up

you can fit some extra in there by filling up the fuel filler hose. I am not sure how long the hose is though I don't think it could fit 1.5 gallons.

when my tank is full my gauge shows 3/4 full and never goes lower then a 1/4. I can fill it about 3/4 full then I have to trickle in the last 4 or 5 gallons. the rest of the jeeps works flawless so I just live with it.

You might want to check your vent hose for kinks. It should fill quickly to shut off

Will do.. I'll add it to my list and let you guys know how it works out.
Thanks for the tip
