BMW E31 Fuel Pump 840i, 840Ci, and 850Ci - 16141182289
BMW E31 Fuel Pump - E31 840i, 840Ci, and 850Ci is a high-quality, complete fuel pump assembly designed for the BMW E31 models with V8 M60 and M62 engines (1994-1999) and V12 M73 engines (1995-1999). This assembly, located under the passenger rear seat, features a redesigned top rubber seal and addresses critical issues found in the original BMW pump design, ensuring reliable performance and longevity.
A major flaw in the original assembly was the tendency for fuel leakage at the parting line due to thermal expansion and contraction. The redesigned top cap is made from stronger materials, effectively preventing cracks and leaks, providing a more durable solution. Additionally, the original brittle plastic fuel lines have been replaced with high-pressure fuel-resistant PTFE lines, improving resistance to modern ethanol-based fuels and eliminating common issues such as rough idling and decreased power.
The new design incorporates military-grade 600V PTFE insulated wiring that provides superior protection against fuel exposure and electrical shorts. The upgraded fuel pump motors, now with carbon commutators, offer enhanced performance, are quieter, and last three times longer than the original copper commutator motors. The new pump motors offer an increased flow rate of 150 LPH, providing improved fuel delivery while maintaining factory-standard 3.5 BAR pressure.
The fuel level sensor has also been improved with more precise and durable components to ensure accurate readings over the long term.
- Leak-resistant design with a crack-proof top cap
- Upgraded high-pressure PTFE fuel lines for enhanced fuel flow and resistance to modern fuels
- Military-grade PTFE wiring ensures long-lasting electrical protection
- Quiet and efficient carbon commutator fuel pump motors
- Increased flow rate of 150 LPH, outperforming the OEM 140 LPH
- Re-engineered fuel level sensor for greater precision and durability
- Easy installation with included components for plug-and-play operation
