diesel filtration system

Basics of Diesel Engine Fuel Systems

The average diesel engine can get somewhere between 400 and 800 miles per tank. But if the filtration system has a fail-point, the system becomes inefficient. Diesel engines are efficient, but it’s also important to understand how the system works to keep the vehicles running at their peak efficiency. Here are the typical components of a diesel filtration system and overall fuel system.

Diesel Fuel Filters

Diesel fuel filters (i.e. full-flow filters) are used to filter diesel fuel several times in the system. The filters help keep particles out of the system that can build up over time and cause efficiency issues with the engine.

Fuel filters are used in any fuel system, but they’re especially important for diesel systems. The reason for this is that diesel fuel is more viscous, and the extra potential for buildup in the system leaves the engine more susceptible to damage. Regularly changing the filters and routine maintenance of the diesel filtration system will help keep the engine running smoothly.

Diesel Fuel Transfer Pump

While a basic fuel system can rely on normal air pressure to distribute fuel throughout the system, a modern diesel system requires a fuel transfer pump. The pump allows fuel to be transferred to the fuel injection system.

Sometimes, an aftermarket lift pump can be installed to increase to improve the fuel system and maintain an optimal PSI for the fuel pressure to ensure long-lasting high performance.

Fuel Air Separation System (FASS)

Combing the lift pump and the filtration system, the FASS combines both into an effective mechanism that helps improve fuel efficiency for diesel engines.

The separation systems are compact and have high-performance fuel pumps that increase longevity and lifespan of the diesel engine’s fuel injection system.

Conclusion

Diesel engines are powerful and efficient combustion engines. But, complex and powerful modern engines require extra filtration and more power than a simple engine. With multiple steps in the filtration process, quality fuel filters are extremely important. And, it’s also important to have a high-performing pump to ensure that the proper fuel pressure is maintained for performance. A combination fuel air separation system can help extend the life of a fuel injection system and improve fuel efficiency. When properly maintained with the best working parts, fuel and filtration systems can last a long time and allow diesel engines to run smoothly.
