The BMW E31 Fuel Pump is a complete, high-quality fuel pump assembly designed for the BMW E31 850i, 850ci, and 850CSI models with M70 and S70 engines (1990-1997). Positioned beneath the passenger rear seat, this assembly includes a top rubber seal and incorporates several key upgrades to correct common issues with the original design.
The primary issue with the original BMW fuel pump assembly was fuel leakage, particularly from the mold parting line located at the top of the unit. Over time, micro cracks formed, resulting in fuel seepage. The newly designed fuel pump assembly eliminates this issue by reinforcing the top cap for a more durable, crack-resistant structure.
Additionally, the original plastic preformed fuel lines have been replaced with high-quality, high-pressure PTFE corrugated fuel lines, making the system more resistant to modern fuels like E10 and ethanol. These new lines provide superior performance by preventing pressure leaks that were common with the older design.
For improved safety and longevity, the wiring has been upgraded to military-grade PTFE insulation, which is highly resistant to fuel and will not degrade over time. The fuel pump motors have also been redesigned, now using carbon commutators instead of copper ones. These carbon motors are quieter, more durable, and last up to three times longer than the original copper commutator motors, providing a reliable and efficient fuel delivery system.
Lastly, the fuel level sensor has been re-engineered with modern components for better precision and durability, ensuring a more reliable fuel gauge.
