are you wanting to keep the original tank? Im not sure where you would put it except in the bed due to it having to stand upright. I am using a tank out of a bronco that i have retro fitted in the chassis behind the axle.
I would NOT recommend you use a kit that uses a fuel cell, ( plastic), as it's base. They are tempting because of their advertised capacity and price, but don't be fooled. Their large capacity causes the cell to hang low in the rear exposing it to road hazards,,, and it looks goofy as well. There are relocation kits being sold that use new stainless tanks, or you can use a tank out of a Blazer. Here is a link to Persh's Idea Page that covers it. http://www.persh.org/pickup/TankBelow.htm Val
My buddy used a Ford Mustang tank (21 gal.). It fit perfectly between the frame rails - he had the tank between the frame rails before he did the step notch.
dval is usually right,.....BUT, i got a 15gal PLASTIC fuel cell from summit racing. fit perfect between the frame rails under the bed. w/bumper or a roll pan you can only see about 1.5" of it...no clearence probs. here...total cost w/cell,fittings/mounts $160.00 ALOT less than a blazer tank... g.t.
if you go plastic just make sure you make a shield that covers the entire bottom and a couple of inches up the sides. plastic is really best for installing in a trunk were its protected. i once lowered and airbagged a friends mazda pickup, you could dump the rear air bags and shoot sparks off the magnesium plate i attached to the rear bumper. what we didnt realize is that he was also dragging the stock steel fuel tank, thus ending up with a hole and leaking fuel down the street. FORTUNATLY he didnt do any spark shows and blow up before finding the leak!!!!
Be careful with the poly tanks/cells if there is no solid support underneath (i.e., straps, or solid mount, etc.)...it will sag and distort the other parts of the tank, such as the bulkheads and filler opening.
No way would I use a plastic tank in a location that is vulnerable to rear end collision damage. I used a stainless steel tank when I relocated mine.
i guess ill change my name to lucky, ive used poly tanks in the past 3 trucks, between the frame rails, in the rear, BEHIND the tailgate,rear sill,and frame....sounds alot safer than the sadle tanks of the 70-80's..... g.t.
fuel tank relocation Somebody mentioned a mustang tank, where do you put fuel in it at? does it fit between the stock rails for a 65? Has anyone found a tank that you can fill behind the tag or something?
My friend located the filler cap through one of the wood planks like most other rear tank kits. The tough thing about a filler cap and neck behind the license plate is that the tank will need to be mounted/located below the frame for the gas to flow down into the tank.
No Limit - Aluminum Tank I bought an Aluminum tank from No Limit and of course it fits perfectly where it's supposed to and has all the necessary filler neck and fuel line goodies. One thing I recommend for sure is to get the fuel tank out of the cab. I'm using the hole for the original fuel tank for a power antennae, and the space behind the seats for speakers and a little storage. I'm also installing a trailer hitch with the receiver in back of the hinged license plate. This will give the tank mega-protection from rear impact. There are all sorts of trick access methods for the filler. Classic Trucks Mag has run a couple of articles about different variations. When I put my bed back in I'm going to simply mount a filler port in the wood strips. There are some pretty nice looking cap systems and since I don't intend on using the truck to haul stuff, it'll look good and shouldn't hurt anything. I'm sorta half-looking for an old fiberglass boat with an old Johnson or Evinrude outboard to tow behind the 65 stepside. I think it'd be a blast to paint one up to match the truck and take them both to the cruise-ins. Ahhh....so much to do and so little time!
