BMW Pressure Hose Assy - Genuine BMW 13537810713

Product Information

The Fuel Injection Pressure Regulator is a critical component of the fuel delivery system that maintains consistent fuel pressure to the injectors. It adjusts fuel flow based on engine demand by regulating excess fuel back to the fuel tank, ensuring optimal air-fuel mixture for efficient combustion. Typically mounted on the fuel rail or integrated within the fuel pump assembly, it helps improve engine performance, fuel efficiency, and emissions control.

• Poor Engine Performance – Loss of power, hesitation, or rough acceleration
• Hard Starting or No Start – Insufficient or excessive fuel pressure affecting ignition
• Engine Misfires or Rough Idle – Irregular fuel delivery disrupting combustion
• Decreased Fuel Efficiency – Excess fuel consumption due to improper pressure regulation
• Black Smoke from Exhaust – Rich fuel mixture caused by excessive fuel pressure
• Fuel Leaks or Fuel Odor – Possible diaphragm failure allowing fuel to escape
• Check Engine Light (CEL) – Triggered by abnormal fuel pressure readings

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.
