Has anyone tried to put a side tank (a 'dual' tank) from the '73-78 body style in an older '67-'72 truck??
I would guess that there is some space conflicts since the 'inner' panel on the box is different. But what about reworking the inner panel on the older style to make room for it?? That just seems to make more sense than leaving the tank in the cab, putting it between the frame behind the rear-end (and thus losing the spare tire space) or just mounting a tank in the boand losing all that space in the box). I realize that reworking the inner panel of the box will 'lose' some space as well, but you could at least still load full 4x8 sheets of whatever in the box!!
It appears that this would 'waste' the least amount of space and still allow for a safer truck. Am I missing something??

The part you are missing is that the frame width on the later model was wider, thus the factory tank doesn't fit between the rails. A better option in my opinion is to get the factory 67-72 auxiliary fuel tank. It mounts between the frame rails in front of the rear-end. It was a common option on the Camper Special trucks, but also available on the other trucks except the 4wd versions.

Don: My understanding is that the auxiliary tank was not applicable for the 4x4 models. I believe there must have been interference with the transfer case. I am more familiar with the F250 4wd models which came equipped with the Dana 24, not the married Dana 21, but I think the issue is the same.
I have a side tank out of a 69 Longbed 2wd in my yard. I had a brake line break behind it along the frame rail so I removed it. I was such a royal pain to get out, I never reinstalled it. Its in Seattle if you want it.
just curious- why bother removing the in-cab tank? i see lots of this type of post. is there something inherently wrong with them, or does everybody just get nervous?
It's not exactly what I'd call 'safe'. I'd prefer not to have the gas inside the cab! Also, the annoyance (sound) of the gas 'sloshing' back and forth when turning as well as the strong gas odors after refueling.
IF I had a leak or a bad seal, I would have strong gas odors all the time. You get gas odors in the cab after refueling because the gas cap and filler is ~2" from the door/window - especially if you happen to 'overfill' or spill any at the neck! They do go away, but I don't really care to smell them at any time while I'm inside the truck!
I just don't like the space limitations in the cab with it there. I did figure that there would be a problem with fitting a side tank on my 4x4 because of the transfer case, did they make a behind the axle tank for these years?
Don
My 69 F100 w/ cab tank and side tank is no pristine thing, but I never had any fume problem w/ my cab tank. The only problem I ever had was parking with the drivers side on a downhill side if I had filled it up completely. I'm thinking if you smell fumes, then you need to look for leak and/or replace rubber filler tube.

There wasn't a "behind-the-axle" tank designed for the 67-72 series, but there is info here about using other tanks, such as a mustang tank, etc. to fit one between the frame rails.
