Ensure Consistent Power with a Genuine BMW Fuel Pump
The fuel pump is tasked with moving gasoline from the tank to the engine at a constant, high pressure. A failing pump can cause sputtering at high speeds, difficulty starting, and a total loss of power. For the BMW M5, using an OEM pump ensures that the system can maintain the massive fuel flow required during aggressive driving.
Worst Drawbacks of Using Aftermarket Fuel Pumps
1. Excessive Operating Noise
Aftermarket pumps are often much louder than factory units, creating a persistent buzz.
2. Unreliable Fuel Level Readings
Generic sending units often provide inaccurate data, causing your fuel gauge to fluctuate or show "empty" when you still have fuel.
3. Shorter Lifespan in Hot Climates
Cheaper internal motors are more prone to burnout when subjected to high temperatures.
4. Inconsistent Fuel Pressure
Aftermarket pumps may pulse or surge, leading to a rough idle or stumbling during hard acceleration.
5. Poor Tank Seal Fitment
The rubber gaskets included with aftermarket pumps are often the wrong thickness, leading to persistent gasoline smells.
6. Incompatibility with Control Modules
Some aftermarket pumps draw too much amperage, which can overheat.
7. Lack of Internal Check Valves
Inexpensive pumps often lack a check valve, causing fuel to drain back into the tank and resulting in long, frustrating crank times.
