The Hilux Toyota diesel fuel tank is one of the primary elements of the fuel system. It is a container which is used to store the diesel needed for internal combustion in the engine. 

The fuel tank is located on the opposite side of the vehicle to the engine for safety reasons.  Fuel tanks are normally manufactured from either welded sheets of steel or aluminium or blow moulded from high-density polyethylene plastic (HDPE).

The fuel tank will have a pipe that connects to it which is used to fill the tank with fuel and this is covered by a flap or cap. The fuel pipe has a filter in it to take out any imperfections in the fuel. Good maintenance of the fuel filter is essential as any imperfections such as paint chips or dirt will cause the running parts of an engine to wear more quickly.  The fuel tank usually has a sensor inside which tells the fuel gauge how much fuel is in the tank and the tank is also designed to minimise the amount of hazardous vapours escaping the tank. The fuel system also has a diesel injector pump, located within the fuel tank. It's an electronic device which delivers fuel under high pressure to meet the demands of the fuel injection engine. Working in conjunction with a computerised control unit, the diesel injector pump pumps the fuel into the engine while ensuring the correct level of pressure is applied to inject the right amount of fuel into the engine at the right time.  The diesel injector pump works by spraying a light mist of fuel into the chambers of the engine, controlled by the computerised control unit, which manages the timing of this process. The injectors are fitted close to the inlet manifold, one for each cylinder, and are all calibrated (adjusted) to equally spray a mist of fuel into the intake of each cylinder in a sequence controlled electronically, for the sequential firing of the engine. The overall result of this ensures the engine is working to its optimum, providing more power and fuel efficiency. 

Problems with the fuel system can cause major problems with the engine. Some issues can include excessive engine smoke or difficulty with the engine starting or loss of power. These are obvious signs that something is wrong, and should be investigated immediately. If the fuel tank has a leak or is damaged in any way it should be replaced as soon as possible. The Hilux Toyota diesel fuel tank is the ideal replacement part, specifically designed to be compatible with the make and model of your car.
