This repair kit is not just a replacement – it is an upgrade. Every component inside the 71901750 kit is manufactured to exacting tolerances, using high-grade steel and advanced polymers that resist wear, corrosion, and thermal stress. The kit includes all necessary seals, gaskets, springs, and pistons to completely rebuild the lift pump assembly, restoring original fuel pressure and flow rates.
Lift Pump Repair Kit contains 12 critical parts, each laser-measured for zero deviation. The primary piston features a diamond-like coating that reduces friction by 22% compared to generic kits. All rubber seals are made of FKM (Viton®) for extreme resistance to diesel, biodiesel, and additives.
After installing the Lift Pump Repair Kit, fleet operators report a 14% improvement in fuel efficiency and a 30% reduction in cold-start hesitation. The precision-machined components restore pump volumetric efficiency to 98.5% of factory-new condition, while the upgraded seal material eliminates leaks even under 1800 psi rail pressure.
Every Lift Pump Repair Kit is calibrated for Howo and Sitrak engine families, including the popular WD615 and MC series. The kit directly replaces the original lift pump internals without modifications. The precision-ground plunger and barrel match the exact OEM specifications, ensuring that the fuel delivery curve remains within factory tolerances.
Fits Howo A7, T7, and Sitrak C7H models.
Tested in temperatures from -40°C to +85°C, the 71901750 repair kit maintains structural integrity and sealing performance in the harshest environments. The anti-corrosion treatment on all steel parts exceeds 240 hours of salt spray testing, making it ideal for coastal or winter-road operations.
All parameters verified against original Howo/Sitrak specifications.
Replacing the lift pump internals with the 71901750 kit is straightforward for any experienced mechanic. Begin by removing the old pump assembly and thoroughly cleaning the housing. Lubricate all new seals with clean diesel or assembly oil before installation. Torque all retaining bolts to 25 Nm ± 2 Nm. After installation, prime the system by cycling the ignition three times to expel air. The 71901750 kit is designed to restore fuel pressure to 5–6 psi at idle, ensuring smooth engine operation.
The elastomers in the 71901750 kit are compatible with diesel, biodiesel (B20–B100), and low-sulfur fuels. They also resist ethanol blends and common fuel additives, making the kit a versatile choice for global fleets. The internal spring steel is zinc-plated to prevent galvanic corrosion.
With the Lift Pump Repair Kit, service intervals can be extended to 150,000 km under normal operating conditions. The upgraded seal geometry reduces leak paths and maintains consistent pressure, which also protects the high-pressure injection pump from cavitation and premature failure.
Every Lift Pump Repair kit undergoes a 28-point quality inspection before packaging. This includes dimensional checks, hardness testing, and leak validation at maximum operating pressure. The kit is backed by a 12-month warranty against manufacturing defects, providing fleets with confidence and reducing unplanned downtime. The Lift Pump Repair Kit is the trusted choice for workshop professionals across Europe, Asia, and the Americas.
