521 fuel tank.

[what]

I Drive my 521 every day. I fuel up once a week. I am thinking of putting in a 15-20 gallon tank in it. What iam thinking about doing is measuring the distance between the frame rails in the back. I have a 70 nova and it has the factory rear mounted gas tank. To fuel the nova you fold down the liscense plate. I dont see why i couldnt put a nova or other large capacity fuel tank between the frame rails in the back and mount a liscense plate with the hinges for fueling. Anybody done anything similar?

I'll be re-locating my tank to the same location when I set up my 2 link. I'll be doing that in feb. If you can hang on that long, I'll get you pics and what tank I use. I've got a suburban/blazer tank I want try. 34 gallons would be nice.

I built a aluminum fuel tank for my 720 exactly as you described. I used a std filler cap I bought from jegs and I cut a hole in the floor of my bed and put a hinge on it so you could hardly see it. If you buy the materials I'd be willing to help ya do this aluminum or stainless steel is the best choice and then you just adapt the stock fuel sender. Takes a while to do,but extra fuel capacity is nice in these little trucks.

i have a tank out of a hardbody it fits great between frame rails and its 15 gallons

Did you put the hardbody tank in your truck k-fed?

I looked at Marine fuel tanks - there's a lot of very useful shapes and sizes.

 

Trouble is they're plastic, I don't know the laws regarding plastic fuel tanks.

The marine tanks? YEah been checking them out on ebay. Plastic would be sweet. No rusting. I will let you know what i do and get. But please keep the ideas coming in.

Iam gonna have to get a liscence plate bracket with the hinges so i can lift the plate to fuel it. Shouldnt be a big deal. Iam looking at the 1979 bronco 25 gallon tank. But iam might have to mount a electrical fuel pump to transfer the fuel the extra distance from the rear of the pickup? Not sure. The stock fuel pump might not have a problem.

[521ofdoom]

I'm not a fan of marine tanks, but that's a personal opinion. Whatever tank you use, i'd look at putting the filler in the bed, a plate filler will probably not be high enough to get good flow.

GOT A PICK RIGHT HERE PIMPIN

[521ofdoom]

Heck yeah! Does it fit with the stock bed floor? I don't want to cut that out other than for the filler hole.

What about keeping the 521 tank and adding a 620 tank (620 is on pass. side) add the 620 filler and you have a dual tank set up that is in the middle of the truck ( better if you get rear ended.)

 

Exhaust will have to be rerouted.
