Problems with aftermarket and increased capacity Fuel Tanks:
I have owned a lot of aftermarket fuel tanks from big to small and from heavy to light. Some fit good, some not so good. Most have been steel tanks which are prone to external rust as well as internal corrosion resulting in increased fuel filter clogging not to mention accelerated internal condensation and moisture resulting in the increased risk of algae growth within the fuel.
The common flat panels of a steel tank inherently results in less overall fuel capacity, heavier in weight, bulkier in size and obviously more noticeable in visual appearance due to it usually being required to hang down significantly lower and reducing ground clearance.
As you can see, the Transferflow tank to the right has been blasted, sanded and repainted several times in it's 6 year life and even with a fresh coat of paint it still looks old and worn. I'm afraid to guess what the inside looks like. The big square boxy tank hangs down quite a bit and it's extremely heavy metal casing made the driver side of the truck lean just a little requiring a 3/4" spacer block in the suspension to even the truck out. The long hollow steel enclosure amplifies underbody noises much like a 55 gallon drum would by sticking your head down in it.
There just has to be a better way.
It's true that anyone can weld a box together and call it a fuel tank. But it takes a lot of resources and investment to design, engineer, machine a mold produce high quality Polyethylene fuel tanks. In the end a Polyethylene tank can utilize every nook and cranny possible, thereby maximizing increased capacity while using less space, resulting in increased ground clearance and even more additional fuel compared to an aftermarket steel tank.
Most stock (or original equipment) tanks are relatively thin and made of materials like Linear Polyethylene. So making a larger, stock tank using stock materials is not the best course of action.
We found that TITAN Fuel Tanks are constructed of High-Density Cross-Linked Polyethylene (XLHDPE), which is bonded molecularly, and we also discovered their advertised nominal thickness of all TITAN Tanks to be a healthy solid 1/4 of an inch.
My wife and I bought a new truck for our 34 year auto parts and speed shop business. we've had other trucks and other bed covers before, but this time around we wanted thee increased capacity fuel tank made. After long and hard research, the answer was undisputable, and the future was clear. We loved this product so much, we became a Titan Fuel Tanks factory dealer!
