OK i just bought a 94 f350 idi. Its 4x4 crew cab long bed it has a big tank along the frame and a smaller one under the spare tire i cant for the life of me find the capacitys for these tanks anywhere on the web. Anybody know? I just know somethins not rite i ran the big tank totaly dry and it barley held 13 gallons. the little one was about half full and it still held 7! this cant be rite can it? with the front tank bone dry and the rear tank half full it only held 20 gallons? thanks for any help

 

only thing i have been able to find so far is either a 16 or 19 gallon on the front and an 18 gallon rear

 

the front tank might have a broken off pickup in it.


and AZ is right, 16 or 19 gallon front, 18 rear unless somone swaped tanks with a bronco or f superduty. it might have a 33 or 38 gallon tank then.

 

ok the truck has been in my family since new so i know the tanks have not been swapped. the broken pick up makes sense to me on the front tank except that i put 13 gallons in it ran it until it ran out on me got under and tapped on it and damned if it didnt sound empty even though it still showed a quarter left. 18 sounds big for the rear by lookin at it where its mounted but what do i know gonna run it down and fill it see what it holds. if anyone has any more input on the front id appreciate it if not then thanks for the info guys.

 

mine has a 12 in the rear and an 18 up front, if you measure the tanks and go to an auto parts store they will tell you by measurements mwhat size your tanks are

 

thats sounds more like it. thanks

 

I have the CHILTON repair manual for pick-ups and broncos here and it says front tank long wheel base diesel 20.0-22.0 gals (varies with model) and for the rear 18.2. I have a 90 crew cab F350 4x4 with dual tanks. The most I've put in the front is 18.5 and the rear 15.5. Both tanks were on E according to the gauge.

 

I have an 88 F0259 ext. cab with 8 ft. bed; what volume are those tanks?

 

12 rear 17 or 19 up front as far as i know

 

My front seems to run out at 12 or 13. Rear looks similar. How could I look it up?
