Filtration System
The 1117211-P301 uses multilayer synthetic and cellulose media designed to remove water, rust flakes, wax sediment, and micro-sized diesel impurities. The filtration system supports precise injector timing and consistent diesel atomization, which helps improve combustion stability and reduce injector strain.
The layered media maintains structural integrity during pressure variation and long service cycles. Stable flow helps ensure predictable power output during loading operation or steady highway travel.
Durable Housing & Structural Design
The reinforced steel housing withstands pressure pulses from Isuzu diesel injection systems. It remains stable during low-temperature starts, extended idling, and heavy-load driving. A rigid internal frame prevents media collapse during high-flow demand.
Fuel-resistant seals help maintain pressure control and long-term durability. The inlet and outlet connections match Isuzu N-Series diesel fuel line geometry for secure installation and consistent sealing integrity.
Flow Stability & Engine Protection
The 1117211-P301 supports steady diesel flow and balanced pressure across the N-Series fuel system. Stable delivery promotes clean combustion, predictable torque, and long-term injector protection. Clean fuel helps reduce the risk of performance instability during high-duty commercial use.
This filter performs reliably in dense city traffic, continuous delivery routes, warm-weather operations, and mild off-road transport scenarios. Its filtration capability supports dependable daily work cycles for commercial operators.
