Hi folks,

i would like to take the fuel tank out of the cab and install a other one under the bed on the passenger side. Has anyone ever done this before?


Greetings from germany

 

You will get a better response if you include more information about your truck. What year is it? Is it a short bed or long bed? Does it have the optional tool box in the side of the bed?

 

That´s right, i forgot all this
It is a 1968 F-100 LWB with a 360 and a C6. There is no tool box in the side of the bed. I dont want the fuel tank between the frame in the back of the axle.


best regards

There is fuel tanks that were made to mount on the outside of the frame under the bed. My 71 crew cab had one tank on each side mounted under the bed at the front. They are nice to have there but the downside and reason why most of us decide to put it between the frame rails is for protection. If you get in any side impact that could be very dangerous. I've taken out my side tanks and will be replacing them with a fuel cell or tank under the bed between the rails. I can take pics of my old tanks when I get bac from vacation if you want.

 

I'd think getting rear-ended is more likely the getting tee boned tho.
But today world red light runner seems to be a new higher rate happening.

I know the saddle tanks were bad on any truck being it a Chevy, Ford or Dodge.
Where as the inner ford frame tank was much safer then any rear or side saddle tanks.

Possibly find a long and narrow tank like a lot of today's pickups use. And find one that will fit that way it's inside the frame rail but still not mounted in the back of the truck. It will also allow you to keep the spare tire.

 

No Ford truck came with R/L saddle tanks.

1967/72 F100/350 Stylesides were available with an optional factory installed 25 gallon auxiliary tank, located on the inside of the left (drivers side) frame rail.

1967/69: Fuel filler tube and exposed fuel cap located above the scallop (Bumpside) line in front of the left rear wheel.

1970/72: Fuel filler tube and exposed fuel cap located below the scallop line in front of the left rear wheel.

Inside the bed is a shield that protects the filler tube from possible cargo damage.

Adjacent to the drivers side of the seat is a manually operated fuel tank selector valve.

Switch located under the dash to the left of the steering column changes the dash fuel gauge from the in-cab tank to the auxiliary tank and vice versa.

Edit: See post #10.

 

Just a thought about rear, inside the frame rails, mounted tanks. The rear bumper, and the rear cross member, protect the tank very well. Many of the newer SUV's, and some older ones, have the tank in the rear, hanging below the frame rails, and are potentially at more of a risk than an old bump, with a tank in the rear. Thinking in reverse, most newer cars, are made of lighter & more plastic materials, hence less impact delivered to an old Bump in an accident. The rear-end collision is no doubt, the most common, but with the lighter cars now days, the odds are in favor of the old Bump surviving with nary a scratch, and the new fly-weight is off to the masher. Like hitting a 20 penny spike, with a tack hammer.

I have thought about researching if a square body GM truck tank would fit outside the frame.
Just a suggestion or thought, rather.

um, I have 2 69 f100's that have dual saddle tanks with a ford "select" lever left of the driverside seat...

 

They're not genuine Ford, they're aftermarket. Ford NEVER installed an auxiliary fuel tank on the right (passenger) side of any F100/350!

Here in CA, The Fey Bumper Co., besides selling their step bumpers, also sold aftermarket saddle tanks which they would install for dealers.

Most of these saddle tanks have the fuel cap located behind a steel or aluminum door, the door frames were riveted to the bedsides.

Genuine Ford =

 

I like the factory under the cab tank, but would put the fill pipe were Gavin put his. i.e. inside the bed, on top of the inner bed wall shelf. Out of the way, out of sight, out of mind. In my '93 Diesel, I have 2 tanks, with the fill pipes behind doors in the driver's side of the bed. I hated my '80 Chebby dually, with a fill on each side. OK, if I never left town, but on a trip, I always had to fill one side, drive out, and turn around. Invariably, some clown would race in and take the pump, as I struggled to turn that beast around. Best vehicle day of my life, was seeing that Bow Tie bumpkin drive off with my headache. I believe that may have been the first "Cash for Klunker" deal .

Hi,

i did not want to put the fuel tank behind the axle, because i would like to put a pop up camper on the bed. I fear, if i put the fuel tank behind the axle, i have too much weight on the rear axle. That's the reason why I'm thinking about, to put the fuel tank in the front of the bed.

Behind the rear axle is really the safest. Today's cars don't take much to crumple so if your rear ended, the impact is not going to come near your tank (tho you may get whiplash and put his engine on his lap, lol)) It would take a train to do any real damage to your truck.

 

Ok, now i´m back with my plan....
You have convinced me that it is not safe to have the tank outside of the frame Now i´m looking for a tank inside the frame. What is a normal price for a tank includet all parts i need?
