I have a 1967 F100, LWB, 2WD, (since 1988) and it's finally getting
the body off resto rod treatment, and the tank is coming out of the cab, I can't seem to figure out when the Ford people did the same thing, I know in '70 it was still in the cab. I no longer use the spare between the framerails, and for traction/wgt want the tank behind the axle, and would prefer not having in the bed, ala pro street style, I'm sure i could make "something" work, but thought if I could start with the first year or two that Ford went that way it would be easier.

Ford stopped putting tanks in the cab in the '73 model year. Frame mounted tanks were available as auxiliary tanks well before that, however. You cannot put a 73+ frame tank in your truck, though, because it will not fit between the narrower frame rails of the 67-72 trucks. You either need to find a 67-72 frame tank or adapt some other tank of the right size to fit. Either way, you will need to fab up a filler. There is a tech article on installing a Mustang II tank, I think, and there are also several discussions on this topic. Do a search for them.

 

MOOOOCHO Gracis (Thats WI pigdin spanglish for thanx)- I do have a side mount aux tank drivers side ahead of rear wheel, takes the place of a brace, but I was getting rid of it too. I did find that they switched in mid 73 right after I posted, but thanks for feed back I'll search the tech info. Trev-CACWBY in WI

 

What do you plan to do with the frame mounted tank (stock) when you take it out? I might be interested in it (and all mounting hardware etc) Where are you located?

Thanks,

I found a tank out of '73 Bronco that will fit in the hole for the spare. I don't have it mounted yet, but there's plenty of room.

I had a 1977 F150 that had the in cab tank behind the seat. I think that in 1978 they switched to putting both tanks under the box.

All trucks from 73 on came with standard frame-mounted fuel tanks. The standard tank from 73 onward is between the frame rails. Prior to 72, the standard tank was in the cab.

Through the 77 model year, however, my understanding is that you could still get an in-cab tank if you ordered it as an auxiliary tank in addition to the frame tank. 73-77 trucks with in-cab tanks are relatively rare, as are 67-72 trucks without them. I have never seen, and don't believe Ford ever offered, a 73 or later truck with only an in-cab tank and no frame tank.

 

Weird, Rockette's Grampa'a 67 F250 Camper
Special didn't have a tank in the cab, but
a pair of frame mounted tanks, one in the
normal aux position, and one behind the axle.
And it all looked stock to me...

Finding an aft-axle tank for a narrow frame is always a discussed topic. I'm just about ready to install a 39-gal Aerotank in my 71 F250. So far, I have to slightly notch a bed rail for a hose-tube clearance. Everything seems to fit OK. I plan to install a Honda fip door (cable-activated) flush with the bed, with a custom fill tube and breather. I plan to take pictures for posting.

Chris,
Please let me know when you post the pics.... I would like to see them. I am planning on taking the tank out of my 71, and putting in a frame mounted. Wanted to put in a flush mount fueling door, with a custom built fuel catch area. I will need to know what is the best way to run the fuel lines along the frame and what kind of fuel sending unit you are planning on unit, so I can have some kind of idea as to what I am going to run into. Are you going to install an electrical, in-line fuel pump? or run the stock motor pump?

Talk to me.........

Thanks,
Strawberry

 

Until I change motors, I will continue to use the stock pump. In fact, I'm actually using a 5-gallon gas can (in my bed) as my tank to pull the truck in and out of the garage, works fabulous for the short trips to the welding shop. I just finished a full cage, so getting a tank in is urgent.

The filler, gas and breather tubes on the tank will be positioned real close to the top inside of the frame. All the hoses will be attached in the little area between the top of the frame, and the bottom of the bed. It's going to be tight, but initial trial fits look good. The tank does hang down a bit (similar to a spare tire), which I'm not crazy about, but it's not too bad, and it is 39-gal. The tank is notched to fit around the rear cross member. I'll probably run a metal gas feed inside the frame rails.

I have to notch and cap a small section of the rear bed rail to fit the tank. I will fabricate a custom filler neck to the Honda flip door. I'll probably have to cut a small section out of the bed, which I'll cover with some sheetmetal work. I may use the stock cover plate used for factory saddle tanks.

The Aeortank comes with a sending unit (same resistance as stock), so apparently the factory gauage should work.

I'm notching the bed rail this week, then hopefully I'll have the tank mounted in another week. Then off to the shop for fabing the neck and flip door.
