I recently purchased a early 99 F250. I got this truck with out doin much research and this truck must have been one of the first built. I have been getting 19-21 mpg which is better than i expected but was curious about the fuel capicity. I have read that these have 28 gallon tanks but the last time i filled up as soon as the fuel light came on and i put in 32.5 gallons with out over filling. Did the early 99's come with a larger tank?

Thanks
Justin

friends 01 f250 regularly fills up with 36 gal. running it almost dry, 780 miles out of a tank. my 99f350 drw takes 36 gallon and i get around 600-650 out of a tank. You may have a problem with the pickup leaving a few gallon in the bottom. there is a section at the top of this website that shows you the fix for getting the most out your tank.

Is yours a long bed? The shortbeds like mine have a 28 gallon tank but if you have a 8ft bed you have the bigger tank. I think its like 36 gallons

i found an 01' crew cab short bed f250 7.3 the other day that has a 36 gallon tank.

Topping off to the top of the fill neck I have squeezed 42 gallons in. It was on a bet and required a lot of rocking.

Reading this thread makes me feel a little better.. I filled up the other day after driving with the light on way longer than I should have, but I was able to nurse 40.625 gallons into her. I was thinking that the pump screwed me out of a few galons but if the capacity is 39 gal on the long beds I could see fitting another gallon or two in the filler neck.

Long beds have a 38 gallon tank, but if you take it slow while filling it up and fill it up all the way, you can easily fit in an extra 3 gallons in the tank after the pump first shuts off.

^^^ Same goes with the "28 gallon" tank. You can really fit about 32 in there if you fill it all the way up the neck.
