This is the updated high pressure fuel pump for BMW's with the N54 or N55 turbo engine. The high-pressure fuel pump is a known weak point on the N54 and N55 engines and can cause limp mode or even leave you stranded if it fails. This is the latest and most current version of the fuel pump offered. Common symptoms of a failing pump include rough idle, engine misfires, sudden loss of power, or failure to start. If your vehicle still has an earlier revision of the pump, especially if it's modified or will be in the future, this is a worthwhile upgrade for improved reliability. Included in the retail price is a refundable $130 core charge.

Sputtering, no starts, or rough idle could be an indication of a failing or failed fuel pump. Also, if your gas gauge is not reading correctly, or not at all, it's probably the level sensor on this pump. Unfortunately, the level sensor is part of the pump assembly and must be replaced as a whole. This replacement Bremmen fuel pump is the perfect option to get your BMW back on the road without draining your wallet.

Experiencing fuel pressure loss or starting issues despite a functioning engine and spark? The likely culprit is your rear fuel pressure pump. This critical component, equipped with a level sensor and mounted inside the fuel tank, is essential for restoring proper engine operation in your MINI.

If your vehicle also features a front High-Pressure Fuel Pump (HPFP), diagnosing a faulty rear fuel pump is simple. When unlocking the car or opening the door, listen for a brief, high-pitched whining noise from the fuel tank—this indicates the pump is priming. If you don’t hear it, the rear pump may need replacement.

Benefits:

Restores consistent fuel pressure for reliable engine performance. Engineered for straightforward installation inside the fuel tank. Easy diagnostic cues help identify rear fuel pump failure quickly. Choose this high-quality replacement to bring your MINI back to peak performance.

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!
