I am wondering why people want to bother going to all the work of relocating the in cab tank?

I don't see a problem with it in my '67 Merc f-100 - I replaced the tank and sending unit from LMC and find it is part of the appeal of the truck to have the cab by the cab and where the tank is. Everyone has their own preferences I guess - that is what makes looking at everyones trucks so interesting.

Thanks!

Im not near my truck at the moment and i dont remember the frame dimensions but with a cross member getting moved im sure this would work. Plus you get 40 gallons of gas.

Alright time to stop procrastinating, gotta get back to studying for the Linear Test.

 

that tank should also work with a diesel conversion because it is not a galvanized tank. Just thought i would put that out there.

 

I installed the Mustang tank behind the rear axle to get some weight on the rear so I would reduce roasting the tires off leaving the line.

 

Something about storing 19 gallons of gas inches away from me i just don't like .

 

I see your point Mike but I do not recall a lot of incidents of these trucks blowing up or injuring the driver. Not the the AMC Pacer

 

true , it's not a pinto . but still i am moving my tank to the back asap .

 

This tank was a factory installed option for all 1967/72 F100/350 Stylesides, it did not come with the Camper Special (C/S) package.

Many C/S's have it...because when the dealers ordered C/S's from FoMoCo, they included this option.

The optional auxillary fuel tank is mounted on the inside of the left (drivers) side frame rail.

1967/69: The fuel filler tube/fuel cap is mounted above the scallop (bumpside) line, in front of the left rear wheel, almost in a direct line from the in-cab's fuel cap.

1970/72: The fuel filler tube/fuel cap is mounted below the scallop line, in front of the left rear wheel.

Inside the bed, butted up to the quarter panel (bedside) is a shield that protects the fuel filler tube from possible cargo damage.

Note: Some 1970/72's have the Evaporative Emission System, have a round hole in the tank where the fuel vapor valve fits into. This tank is 22.5 gallons.

You DO NOT want to install a Chevy/GMC auxillary fuel tank that was originally installed on the OUTSIDE of the left frame rail, butted up against the sheet metal.

When these trucks were T-boned or side swiped, the tanks split open, gas poured out and exploded. Some peeps that were trapped inside the cabs, burned to death!

This was the second exploding fuel tank FIASCO, occurred just after the exploding Pinto fuel tank FIASCO.

The Pinto fuel tank was made in two sections, upper and lower. These two halves were spot welded together forming a 3/4" seam that protruded from the tank.

When these cars were rear ended, the tank was pushed forward, the seam of the tank hit the rear axle's center section, split open, gas poured out and exploded.

This action also pulled the fuel filler tube from the tank, causing more fuel to pour out.

1965/73 Mustang fuel tanks are made the very same way! So go right on ahead and install one a these tanks in your truck, but you have been forewarned.

The same chain of events could occur w/a Mustang tank installed in these trucks...that occurred with the exploding Pinto fuel tank FIASCO.

 

Yes Bill, but the Pinto was a unibody construction and did not have a truck frame surrounding the fuel tank. My truck was sitting still when some kid rear-ended me going 40mph and the rear frame section where the under bed spare sits was not compromised.

 

Well the suburban tank is not the saddle bag type tank it sits between the frame rails.

 

i have a 1/4 steel step bumper , probably weighs 100lbs if they get through that then so be it .

 

You forgot the hitch lol. They have to go through hitch, big bumper, frame, then gas tank.

 

Friend of mine in Van Nuys owns 3 1960 Lincoln's, be thankful that kid wasn't driving one a those, or you might be playing a harp, instead of typin' on FTE.

This applies to all y'all. Don't think for a moment that a step bumper, and/or hitch with pickup frame rails will save your life.

These trucks do not have any safety feature besides seat belts, and most are lap belts, cuz shoulder straps were optional.

 

Well not to seem like a horses a$$ where would you recommend putting it. Some people need the storage behind their seat

 

Optional 25 gallon factory installed auxillary tank. And...when the optional in-cab storage compartment was ordered, this tank became a mandatory order, because...
