If you don't already have the fuel cans, it will take a long time to offset the cost and effort to purchase them.

You probably don't want to handle anything larger than 5 gallons, as gasoline is about 6 lbs per gallon.

Why would the fuel cell have to be inside the car if itís replacing the existing tank? I donít see why it would have to be if all the connections for vapor recovery and fuel return were located on it...

The last time I maxed the fuel savings was back when diesel was above $4/gallon. The truck took 25 gallons, which was the limit for fuel savings, and cost exactly $100 after discount. Very depressing to have "saved" so much, having spent $100 to get 70% of a tank of fuel.

Around the same time I also put $20 of fuel into the truck, and it didn't even turn the low fuel light off.

The existing tank is likely very oddly shaped and takes advantage of lots of available space.
Have you seen the stock tank?
Fuel cells come in 2 common shapes, cube and rectangular prisem in all different sizes and then custom for the most common race car converts, where the manufacturer just copies the stock design of the original tank.
I don't see it being possible to get a gas tank for a modern car that holds 5 or 10 more gallons.

Yeah, you'd probably have to remove the rear seat, or allow the tank to hang dangerously low to the ground.

I DO have a trailer receiver, but would I want to carry around an extra 15 gallons of gasoline on my rear rack waiting for someone to rear end me? Guess I'm stuck with the 10 of 25 refill savings.

Don't cheap out transporting fuel. The install above is a range extender, it almost doubles the capacity 11 —> 21 gallons. With the NATO-style can with the locking pin in the latch you can throw them off a tank and they still work.

If you put those on a hitch mount, they'd squirt like a pumpkin seed before they crush in a rear-ender.

Very nice! Or, I could store the full cans in my garage. Of course, at $70 a piece, it would take 280 gallons of gas at $.50 per gallon discount, (or about 11,000 miles of driving) to reach the payback point.
Not TOO bad an investment. What if I hitch mount them, and insulated them from the sun and thieves with a locking cover box? will they still squirt?

In my case there was some value in justifying the investment in that stress bar. I saw the invoice the other day, $130 — so you're not far off.

But you have to use the same debit/credit card. I'd have to have a friend who can go to the pump when I do, and pay me back for their part, and then, I'd still only save on my 10 gallons.
