Fuel capacity??

[FordPowerStroke1986]

I have an early 99 f250. Ext cab long bed. One tank. I'm trying to figure out how much it holds.

[Degnol]

I don't know whether the bed length or the cab dictates the tank size, but my CCLB holds 38 gallons.

38 gallons.

[Austin G]

Longbed = 38 Gallons
Shortbed = 26 gallons

Thanks for the info guys. That explains why I got 400 miles on a tank

[Luckyjhorses]

OH MY!!! I am gettin almost 700 miles to a tank...

well i have been goosing it around alot cuz i just got my CTS. So i just put it back to stock and when i hit the lottery i will fill up again and take it easy to see how much mileage i can get out of it. The only mod i have right now is a DIY intake with a Donaldson filter. I do have my stock exhaust cut off just before the muffler so i guess i could say its straight piped I intend on doing a 5" turbo back when i get some money.

shortbox is 32 gallons, not 26.
longbox is 38, but on my 99 when it was dead empty, and I filled it to the rim after waiting for the foam to subside, I got 41 and change in it.
