What is centrally mounted fuel tank?

The rear of the fuel tank bracket is now attached to a heavy duty central mount via a single 16mm heim joint (spherical plain bearing rod end). The mount is bolted directly to the chassis cross member, both horizontally and vertically, which gives it more strength.

A fuel tank (also called a petrol tank or gas tank) is a safe container for flammable fluids, often gasoline or diesel fuel. Though any storage tank for fuel may be so called, the term is typically applied to part of an engine system in which the fuel is stored and propelled (fuel pump) or released (pressurized gas) into an engine. Fuel tanks range in size and complexity from the small plastic tank of a butane lighter to the multi-chambered cryogenic Space Shuttle external tank.

Typically, a fuel tank must allow or provide the following:

Plastic (high-density polyethylene HDPE) as a fuel tank material of construction, while functionally viable in the short term, has a long term potential to become saturated as fuels such as diesel and gasoline permeate the HDPE material.

Considering the inertia and kinetic energy of fuel in a plastic tank being transported by a vehicle, environmental stress cracking is a definite potential. The flammability of fuel makes stress cracking a possible cause of catastrophic failure. Emergencies aside, HDPE plastic is suitable for short term storage of diesel and gasoline. In the U.S., Underwriters Laboratories approved (UL 142) tanks would be a minimum design consideration.

While most tanks are manufactured, some fuel tanks are still fabricated by metal craftsmen or hand-made in the case of bladder-style tanks. These include custom and restoration tanks for automotive, aircraft, motorcycles, boats and even tractors. Construction of fuel tanks follows a series of specific steps. The craftsman generally creates a mockup to determine the accurate size and shape of the tank, usually out of foam board. Next, design issues that affect the structure of the tank are addressed - such as where the outlet, drain, fluid level indicator, seams, and baffles go. Then the craftsmen must determine the thickness, temper and alloy of the sheet he will use to make the tank. After the sheet is cut to the shapes needed, various pieces are bent to create the basic shell and/or ends and baffles for the tank. Many fuel tanks' baffles (particularly in aircraft and racecars) contain lightening holes. These flanged holes serve two purposes, they reduce the weight of the tank while adding strength to the baffles. Toward the end of construction, openings are added for the filler neck, fuel pickup, drain, and fuel-level sending unit. Sometimes these holes are created on the flat shell, other times they are added at the end of the fabrication process. Baffles and ends can be riveted into place. The heads of the rivets are frequently brazed or soldered to prevent tank leaks. Ends can then be hemmed in and soldered, or flanged and brazed (and/or sealed with an epoxy-type sealant) or the ends can be flanged and then welded. Once the soldering, brazing or welding is complete, the fuel tank is leak-tested.

In the aerospace industry, the use of Fuel Tank Sealants is a common application for high temperature integral fuel tanks. This provides excellent resistance to fluids such as water, alcohols, synthetic oils and petroleum-based hydraulic fluids.

A larger fuel-tank results in a greater range for the car between refills, however the weight and space requirements of a larger tank are undesirable, especially in smaller cars. The average fuel tank capacity for cars is 50–60 L (12–16 US gal).

The most common materials for fuel tanks are metal or plastic. Metal (steel or aluminium) fuel tanks are usually built by welding stamped sheetmetal parts together. Plastic fuel tanks usually built using blow molding, which allows more complex shapes to be used.

Some vehicles include a smaller reserve tank to be used when the main fuel tank is empty. Some other vehicles, typically 4WD vehicles, have a large secondary tank (or "sub-tank") to increase the range of the vehicle.

A racing fuel cell has a rigid outer shell and flexible inner lining to minimize the potential for punctures in the event of a collision or other mishap resulting in serious damage to the vehicle. It is filled with an open-cell foam core to prevent explosion of vapor in the empty portion of the tank and to minimize sloshing of fuel during competition that may unbalance the vehicle or cause inadequate fuel delivery to the motor (fuel starvation).

Aircraft typically use three types of fuel tanks: integral, rigid removable, and bladder.

Fuel tanks have been implicated in aviation disasters, being the cause of the accident or worsening it (fuel tank explosion). For example:

In some areas, an aircraft's fuel tank is also referred to as an aircraft fuel cell.

Water supply systems can have primary or backup power supplied by diesel-fueled generators fed by a small "day tank" and a much larger bulk storage fuel tank.

Proper design and construction of a fuel tank play a major role in the safety of the system of which the tank is a part. In most cases intact fuel tanks are very safe, as the tank is full of fuel vapour/air mixture that is well above the flammability limits, and thus cannot burn even if an ignition source were present (which is rare).

Bunded oil tanks are used for safely storing domestic heating oil and other hazardous materials. Bunding is often required by insurance companies, rather than single skinned oil storage tanks.

Several systems, such as BattleJacket and rubber bladders, have been developed and deployed for use in protecting (from explosion caused by enemy fire) the fuel tanks of military vehicles in conflict zones.

For stationary fuel tanks, an economical way to protect them from hazards like extremes of temperature and vehicle crashes is to bury them. However, buried tanks are difficult to monitor for leaks. This has led to concern about environmental hazards of underground storage tanks.

To recap a little about my how I initially did my new fuel system setup…

If you are interested in reading that article first, click here!

Unfortunately, not until everything had been installed and setup did I realise that there was a real problem with the initial fuel tank bracket.The nuts on the bolts that secured the tank bracket to the chassis rails were virtually inaccessible when the tank was fitted. This meant that if I ever needed to remove the tank, it would be a challenge. Well, that’s a bit of an understatement… it would have been virtually impossible.

This modified fuel tank bracket definitely resolved the initial removal problem, but I had started to question myself about whether or not this fuel tank bracket would adequately withstand the rigours of off road use. After hearing from someone else that had encountered issues with his centrally mounted fuel tank I decided that a different design was probably warranted.One factor that I did not really pay enough attention to when designing the first to iterations of the fuel tank bracket was the chassis flex that occurs when the truck is undergoing articulation. With a solidly mounted fuel tank bracket, like the first two that I built, any torsional stresses that develop would be transferred directly into the fuel tank. This would likely result in one or more of the welds in the tank fracturing.As is too often the case, Murphy’s Law would probably have this happen at the most inopportune time, so it was back to the drawing board.I cannot really understand why I did not factor the chassis twist into my original fuel tank bracket designs, but I definitely didn’t.

I tested a few different designs, finally settling on a three point mount system. So, a third version of the fuel tank bracket was built.

The fuel tank bracket, now only being secured in three locations, is not as torsionally strong as it was previously. I was concerned initially that there was too much flex in the bracket itself, but then I realised that when the fuel tank is strapped to the bracket that the tank will add quite a bit of additional strength, making the fuel tank and bracket setup quite rigid. This is mandatory, as I don’t have a large amount of clearance between the fuel tank and the insides of the chassis rails; enough clearance to allow for chassis flex, but not a lot more.
