HIGH-PERFORMANCE ALUMINIUM FUEL TANKS FOR MOTORSPORTS

A car fuel tank is a container used to store fuel in vehicles equipped with internal combustion engines. As automobiles constantly require gas, petrol, or diesel fuel, it is essential to have a built-in tank. Fuel tanks are typically constructed using plastic, steel, or aluminum. 

In most cases, fuel tanks sustain damage from car accidents or corrosion. Damaged steel or aluminum tanks can be welded, while plastic tanks often require replacement. However, dismantling the tank is a costly process as it involves disassembling several other car components. It is common for the fuel tank cap to be lost during refueling, prompting the need to purchase a replacement cap. Modern cars often have caps attached to the vehicle, eliminating the risk of losing them.

HOW TO IDENTIFY CAR FUEL TANK MALFUNCTIONS

To detect any malfunctions in the fuel tank, you should inspect it for damage and leaks. If any damage or leakage is found, immediate repair is necessary. Additionally, measure the pressure within the fuel tank, which should be within the specified range mentioned in the vehicle’s technical documentation. If the pressure is below the optimal value or no pressure is observed, check the ventilation system of the tank.

You may notice that the fuel tank requires diagnostics if you experience the following symptoms:

• The engine’s performance has deteriorated.
• The vehicle’s maximum power has decreased.
• There is a significant increase in fuel consumption.
• A fuel odor is present in the passenger compartment.
• The engine misfires at low rpm.
• Jerking movements occur while driving.
• Traces of fuel leakage are found on the tank or beneath the vehicle.

CAUSES OF FUEL TANK MALFUNCTIONS

Fuel tank malfunctions can result from fuel system depressurisation, ventilation system failure, or improper operation of the evaporative emission control system. Worn fuel supply valves or roll-over valves can cause excessive fuel vapor pressure to build up in the tank. This can be easily identified by unscrewing the fuel tank cap, which will result in a distinct hissing sound.

Using poor-quality fuel or leaving the vehicle with the fuel tank neck open for an extended period can lead to clogging of the fuel supply line, the entry of foreign substances, dirt, and water into the tank, as well as condensation of water inside.

It’s important to note that fuel tanks are susceptible to natural wear, metal tanks often rust and need to be repaired or replaced. Therefore, it is advisable to regularly check the tank for any fuel leakage. Leakage may also occur due to a hole in the tank caused by sudden impacts on rough terrain or road accidents.
