New F250 super duty with turbo diesel, tourqe shift trans. Crew cab (full 4 doors) with short bed configuration.

I just filled my tank for the first time. It's supposed to hold 29 gallons. I put in 29.5! The fuel alarm did not yet go off gauge still said 3/16th tank left. Everything that came with the truck, the salesman and the specs on the computer all say 29 gallons only!

I think they gave me the 38 gallon tank. We measure one of trucks with a known 38 gallon tank...the dimensions are the same.

Anyone have any similar questions?

I don't want to run it out of fuel.

Thanks,
Tedd

 

Whats the best milage your getting? With or without a chip.

Key words in the specs "nominal capacity." Translation: "about."

 

I'm suspicious of the pump measurement where you filled up. Did you "top off", dribbling the last few gallons in? Maybe you had fuel sucked up in station's vapor recovery system. (Do diesel pumps use vapor recovery?)

 

I don't think so, diesel is much less volatile than gasoline.

I think you have a 29, and you may want to suspect the measurement. Most folks with a 29 and without a harpoon can't get near 29 gallons.

 

I can fit over 30 into my 29 gallon tank without trying, 31.5 if I try. The fuel gauge goes down a lot quicker at the bottom also, don't worry about it.

 

With my 04 F-250 shortbed & harpooned tank I put in 32 gallons on more than one occassion. It was on Empty (and long enough I was in worry mode), with Lie-O-Meter indicating less than 10 miles to empty.

I amy be wrong, but I thought 4x4 Diesels had a 39 gallon tank and 2wd diesels had the 29 gallon tank
But I am sure that there is or could be a difference with a short bed vs long bed
just trying to help
I have a 2002 F-350 4x4 long bed with the 39 gallon tank

 

I have the short bed and have the 29 Gal. tank...I WISH I had a 38Gal. tank..that'd be AWESOME...I go to SW Missouri quite often and its 500 miles exactly....nice to be able to do it wothout stoppin for push-water!

shortbeds have 29 gallon and long beds have the 38 gallon.

it is an approximate amount. there is a vapor area for the gas models because gas needs it, diesel fuel doesn't.

so if you fill up to the top and dribble the fuel in slowly, you can get about 30 gallons in approxmatly.

there is the harpoon mod which all it does is remove the vent tube from sticking inside the tank (or something like that) so you can fill it to the top faster without the nozzle constantly tripping off or fueling slowly.

 

bf250 can you tell excatly what you do on the harpoon mod, seen some post but non descripe it to tell what's going on.

 

I would not be complaining. I wish I could put 38 gallons in my rig! Congrats!

 

This is the first time I ever heard anyone complain about this

 

I regularly fit more than 29 gallons in my tank on (which is suppose to hold 29)

I've put as much as 29.75 gallons in when it wasn't even completely empty. I probably still had a gallon or more in there.

 

Diesel vehicles do not have any vapor handling systems at all to my knowledge. There is a vent on the top of the tank when you have a diesel and that's it.

The tank is definitely bigger than the advertised capacity for the Crew Cabs with short boxes. I have an 04 with a bone stock tank. One time I had 525 miles on the trip and put 28.2 gallons in it. My low fuel light never came on. Now, look, if it really had 29 available, that means it only had .8 gallons in there? That is below 1/32 of a tank! The light should have been on, and I could swear that I had read somewhere that the light is supposed to come on when your computer thinks you have less than 75 miles left on the tank. I know it works, too, because I ran a heavy trailer to about 350 miles and the light was glowing brightly.
