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.

• Eliminates fuel leaks caused by cracks in the original design
• High-pressure PTFE fuel lines for enhanced durability and resistance to modern fuels
• Military-grade PTFE insulated wiring for greater longevity
• Upgraded carbon commutator fuel pump motors for quieter operation and longer life
• New pump motors deliver 150 LPH, offering improved fuel delivery over the original 110 LPH
• Re-engineered fuel level sensor for better accuracy
• Plug-and-play installation with all necessary components for a seamless fit

If you encounter fuel pressure loss or starting issues despite a functioning engine and spark, consider replacing this unit—a common culprit in such situations. This fuel pressure pump with a level sensor, mounted inside the fuel tank, is the solution to restore your Mini's engine operation.

It's an effective method to diagnose a faulty rear fuel pump when there's a front High-Pressure Fuel Pump (HPFP) in place. Simply check if you can hear the rear fuel pump prime when opening the door or unlocking the car. Listen for a high-pitched, brief whining noise originating from the fuel tank, lasting only a couple of seconds. If absent, it indicates an issue with the primary rear fuel pump.

• Restores fuel pressure for proper engine function
• Designed for easy installation within the fuel tank
• Diagnostic feature helps identify faulty rear fuel pump
