Pierburg fuel pump Performance Parts & Modifications

When it comes to fuel delivery, reliability is everything—especially in performance and OEM applications. That’s why mechanics, tuners, and enthusiasts around the world trust Pierburg, a German-made brand with a long-standing reputation for precision and quality. Whether you're running a street car, 4x4, or custom build, a Pierburg fuel pump gives you consistent fuel flow with the peace of mind that comes from OE-grade components.

At Empire Performance, we stock the Pierburg 5–9 PSI Lift Pump because it's a proven performer. Designed to deliver around 90 litres per hour at low pressure, it’s ideal for use as a pre-pump or for filling surge tanks in both petrol and E85 applications. Built with reliability in mind, it’s a pump that does its job quietly, efficiently, and without fuss—exactly what you want from a fuel system component.

What’s Included & Technical Specs

This Pierburg lift pump (Part Number: 7.21440.53.0) comes ready to install with a mounting bracket included for easy fitment. Both the inlet and outlet are 5/16" (8mm) barbs, making it compatible with standard fuel line setups. The pump runs at 5 to 9 PSI, with a flow rate of approx. 90 LPH, making it perfect for feeding surge tanks or acting as a low-pressure supply pump in staged fuel systems.

One standout feature is its compatibility with E85 fuel, which makes it suitable for modern performance builds. It can even operate on 6-volt systems, though pressure and volume are halved.

Performance, Reliability & Fuel Compatibility

Built in Germany to the strictest OEM standards, Pierburg pumps are known for their long-term reliability and quiet, vibration-free operation. In setups where consistent fuel supply is critical—such as high-performance street cars, off-road 4WDs, or track builds—this pump delivers.

It's also one of the few low-pressure pumps on the market that works seamlessly with ethanol-based fuels like E85, giving you greater flexibility with your build. Whether you're running a tuned turbo setup or just upgrading your factory fuel system, this pump is built to handle the job day in and day out.

Installation & Ease of Use

Installing the Pierburg lift pump is straightforward thanks to its compact design and included mounting bracket. The 5/16” barbed fittings suit standard fuel lines, and it can be installed in-line with minimal fuss. It’s an excellent choice for those adding a surge tank or upgrading the lift stage of a dual-pump setup.

If you’re working with a 6V classic vehicle or motorcycle, this pump also has the flexibility to run on lower voltage, making it a versatile choice for older or specialty vehicles. Whether you’re a weekend DIYer or a professional installer, this is a no-nonsense component that fits, works, and lasts.
