More efficient fuel system for high-power BMW S58 engines.

The BAR-TEK® low pressure fuel pump upgrade kit is a high-flow solution for BMW's S58B30 engine, found in models such as the G8X-generation BMW M2, M3, and M4. The system is based on OEM components and has been developed in conjunction with Walbro high-flow pumps specifically for high-power configurations.

The kit is ideally suited for engines with power levels reaching up to over 1000 horsepower, in both petrol and ethanol (E85) use.

Two Walbro pump options available

Walbro 450

• suitable for up to approx. 1000HP

Walbro 525

• suitable for up to approx. 1200HP

Integrated into OEM structure

The additional Walbro pump is integrated directly into the original fuel pump basket.
BAR-TEK uses a CNC-machined aluminium manifold for this purpose, into which are integrated:

• external fuel lines

• connections

• fuel pressure regulator

All connections are made with PTFE fuel lines and quick connectors, ensuring a reliable and secure installation.

Beneath the manifold is a stainless steel micron filter, which solves the clogging problem of unserviceable original filters.

Ready for return line system

The structure includes a separate connection for the fuel return line, allowing the use of an external fuel pressure regulator.

• in standard installation, the connection is closed

• can easily be upgraded later to a return fuel system configuration without changing the pump

Reliable electrical control

Each kit includes a high-quality Hobb switch, which ensures proper electrical control of the pump and reliable operation under various load conditions.

Pre-assembled option

As an additional service, the pump can be ordered as a pre-assembled unit:

• new original fuel pump basket

• all components pre-installed

• unit tested before delivery

This allows for plug & play installation using original connections.

Compatibility

Fits the following BMW models equipped with the S58B30 engine:

• BMW M2 (G87)

• BMW M3 (G80 / G81)

• BMW M4 (G82 / G83)
