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.

BMW N54 N63 N74 Injector Seal is a crucial component for maintaining the performance and efficiency of your BMW's fuel injection system. This high-quality seal, located at the end of the injector, ensures a tight fit, preventing fuel leaks and maintaining optimal engine operation. Each seal is sold individually, with one required per injector, making it an essential part of any injector maintenance or replacement.
The O ring that is located on the engine side of the injector. Best to replace whenever removing the fuel injectors for any reason.
If you drive a European vehicle, chances are high your vehicle came equipped with one or more Victor Reinz gaskets. Choose OE quality VR gaskets and seals and do the job right the first time.
Measurements: 9.2x2.8

These o-rings need to be replaced any time that the fuel injectors are pulled. These have a habit of swelling and can tear or suffer other damage when being reinstalled or when removed. If the seal is not tight, this could lead to a fuel leak or worse.This Elring o-ring will ensure the seal is nice and tight
Elring is one of the biggest OEM names in the manufacturing of high quality gaskets that are available for very affordable prices. Elring has supplied many automotive names for years with the gaskets that seal your car's components from day 1 so you can rest assured that these components will last for a long time to come!

The Precision Raceworks G8x/G2x Stand Alone Auxiliary Fuel System is the highest-performing and most stable low-pressure fuel system on the market! Forget about how things have been done and embrace the benefits of dedicated fueling for your port injection!
Since direct injection came out for BMW, enthusiasts have been adding port injection. With this came the need to upgrade the low-pressure fuel system to keep up. Historically this was done by increasing the output of the main fuel system. Unfortunately, the main fuel pump is controlled using PWM by a factory programmed controller designed to reduce output when target fuel pressure (typically 5 bar) is exceeded, creating a constant battle when pumps are added or upgraded. This limits upgraded fuel pumps from performing to their full potential.
Additionally, the high-pressure pump control system dumps fuel back into the low-pressure system at high pressure low volume resulting in oscillations of the low-pressure fuel system. Because of this, the DI system in the car is required to constantly make corrections to keep target AFR in check.
With this stand-alone low-pressure fuel system dedicated to your port fueling that is a thing of the past! Get rock-solid fuel pressures at any pressure, run fuel pressures that are 1:1 scalable to boost pressure, flow more fuel with dedicated lines, run smaller injectors and still get more fuel than you did with large injectors (allowing for higher resolution), put less demand on the car’s DI system to correct for fluctuations in pressure, even your tuner will be grateful as the system makes tuning of port fueling even easier and more accurate, the list of benefits goes on and on!
