Veikimo principai
The AEM 50-1200 is an electric in-tank fuel pump designed to draw fuel from the vehicle's fuel tank and deliver it under pressure to the engine's fuel injection system. It utilizes a gerotor-style pumping mechanism, known for its efficiency and durability, especially with various fuel types including ethanol and methanol. The pump maintains a consistent fuel pressure and flow rate, ensuring optimal fuel delivery for high-performance applications.
Priežiūra
Proper maintenance of your fuel system components, including the fuel pump, is crucial for longevity and performance. While the AEM 50-1200 fuel pump itself is designed for durability, regular checks of the surrounding system are recommended.
- Kuro filtro keitimas: Regularly inspect and replace your vehicle's external fuel filter as per the vehicle manufacturer's recommendations. A clogged fuel filter can put undue strain on the fuel pump.
- Pre-filter Inspection: If accessible, periodically inspect the fuel pump's pre-filter (strainer) for debris and clean or replace if necessary.
- Sistemos nuotėkiai: Periodically check all fuel lines and connections for any signs of leaks or damage. Address any leaks immediately.
- Elektros jungtys: Ensure all electrical connections to the fuel pump are clean, secure, and free from corrosion.
- Kuro kokybė: Use high-quality fuel to minimize contaminants that can affect pump performance and lifespan.
