Products Description

This is the 1003726161 electric fuel pump motor matched with heating fuel primary filter base, exclusive core engine spare part for SHACMAN heavy-duty trucks. It cooperates with the fuel coarse filter heating support assembly to automatically extract diesel fuel for engine oil supply. With built-in oil pumping capacity and matched heating base, it effectively solves cold start difficulty and diesel waxing pipeline blockage under low temperature environments. Made of wear-resistant, anti-corrosion raw materials, it maintains stable fuel delivery performance under long-distance heavy load and harsh cold weather. Fully compliant with OEM specification, sturdy structure and plug-and-play installation, ideal OEM replacement component for SHACMAN Delong X3000, X5000 trucks equipped with Weichai WP13 engine.

② Adaptable System: Perfectly matches original engine fuel coarse filter heating base assembly. Fits factory fuel pipeline, filter seat and wiring harness precisely for direct installation, no cutting, drilling or structural modification needed.

③ OE Reference Number: 1003726161

④ Interchangeability: Produced strictly to OEM original dimension standards, including thread size, wiring port, mounting hole position and oil circuit interface. Direct one-to-one swap with original factory parts, fast disassembly and assembly to save maintenance time and labor expense.

⑤ Value-added Service: We confirm full compatibility by verifying your truck model, engine model and VIN code. We supply complete installation guidance, circuit connection steps and daily maintenance tips, effectively preventing pump burnout or fuel supply failure caused by incorrect operation.

Materials & Craftsmanship

Core Materials

This electric fuel pump motor adopts high-strength metal rotor assembly and oil-resistant sealing rubber ring. It can withstand long-term diesel immersion, fuel pressure impact and continuous engine vibration, effectively resisting rubber aging and internal oil leakage. The built-in high-efficiency drive coil maintains stable pumping power without power attenuation under long-time continuous operation. Thickened metal shell provides excellent shockproof and rustproof performance, perfectly adapting to the damp, dusty and low-temperature chassis environment. The internal filter screen blocks tiny impurities to avoid motor jamming, guaranteeing smooth fuel circulation all year round.

Surface Treatment

All metal components of the pump body are finely machined via CNC equipment, which ensures precise thread and mounting dimensions. The outer housing gets an electrophoretic anti-rust finish to stop damage from diesel fuel, muddy water and roadside dust. Reinforced insulated wiring terminals guard against short circuits triggered by constant chassis vibration or water splashes. Internal seals are coated with a special oil-resistant layer. They won't swell or leak even after prolonged contact with diesel, so the pump maintains steady fuel delivery no matter the working environment.

Production Craftsmanship

We adopt mature integrated assembly and sealing production technology to ensure the whole pump is solid and leak-free. All core dimensions are controlled within OEM tolerance range during production to achieve seamless matching with original filter base. Every finished fuel pump undergoes rigorous multi-item inspections: fuel delivery pressure test, sealing leakage test, long-time fatigue aging test and low-temperature simulation test. All finished goods are fully inspected batch by batch to eliminate defective products. Production standards fully follow Weichai original factory norms, reaching the same service life and working performance as OEM spare parts.

Production Capacity

We own automated assembly production lines and professional multi-functional testing equipment. Stable monthly output and sufficient spot inventory can fully support bulk wholesale and large-volume export orders. Custom service is available for special interface, wiring and specification requirements; free sample supply is supported to meet purchasing demands of global truck spare parts dealers, repair workshops and vehicle manufacturers.

FAQ

Q: What advantages does this fuel pump have over ordinary aftermarket pumps?

A: It is equipped with high-precision rotor structure and multi-layer oil-proof sealing design, much more durable than universal fuel pumps. It resists low-temperature wax blockage, long-term vibration and diesel corrosion, with zero oil leakage risk. Standard OEM size ensures perfect fit with SHACMAN WP13 heating filter base, providing steady fuel supply and eliminating cold start failure.

Q: Is the product reliable? What's its service life?

A: Every single pump is produced according to OEM standards and passed independent sealing, pressure and aging tests. With outstanding shockproof, anti-corrosion and stable pumping performance, its normal service life reaches 2–3 years under standardized maintenance, perfectly suitable for cold area long-haul heavy transport and daily frequent use.

Q: What benefits can you get after replacing this pump?

A: It recovers stable automatic fuel supply, thoroughly solves hard cold start, insufficient oil supply and flameout problems caused by damaged original pump. It reduces extra wear on engine fuel system and filter assembly, lowering subsequent maintenance costs. Meanwhile, it greatly improves vehicle startup stability and driving safety in cold weather.
