Installation Protocol
Tools Required: Fuel line disconnect tool, torque wrench (8 Nm), OBD-II scanner (e.g., Jaguar SDD).
Critical Steps (per SAE J2716):
Depressurize System:
Disconnect battery → Relieve fuel pressure via Schrader valve → Drain residual fuel.
Pump Replacement:
Remove rear seat → Unbolt access panel → Replace O-ring (use fluoropolymer-compatible grease) → Torque assembly to 8 Nm.
ECU Reset:
Scanner → Fuel System → "Reset Adaptation Values".

Durability of fuel pump assembly
The durability of fuel pump assembly depends on material selection, manufacturing process and service environment. High strength and corrosion-resistant materials are used to optimize the internal structure design, which can improve the wear resistance and fatigue resistance. Regularly maintain the fuel system, keep the filter clean and the oil circuit unblocked, and prevent impurities from entering the pump body.
Competition pattern and major enterprises of fuel pump assembly industry
The competition pattern of the fuel pump assembly industry is diversified. The global market is dominated by international giants such as Bosch, Denso and Delphi, which occupy a leading position in technology research and development and market share. In the Chinese market, Wanxiang Group, yinlun and other local enterprises have gradually improved their competitiveness through technological innovation and localized production. With the rapid development of new energy vehicles, enterprises focusing on electric fuel pumps, such as BYD and Great Wall Motors, are also emerging in the market
