Precision Raceworks Bucketed Low Pressure Pump Upgrade (Non-Modular) - BMW E9x/E8x

The Precision Raceworks Bucketed Low Pressure Pump Upgrade is a fixed-stage version of Precision Raceworks' E9x/E8x bucketed pump line, built around a single genuine Walbro pump capable of flowing up to 350% more fuel than the factory unit. Both stages are 100% E85 compliant and ship fully assembled and ready to drop in.

This is the right choice if you already know the horsepower level you are building toward and do not plan to go higher later. If you might want more headroom down the road, Precision Raceworks' modular bucketed pump covers the same platform with an upgrade path built in.

Choosing Your Stage

• Stage 2 (2.6 LPM): Single Walbro 450. Up to 575 whp on pump gas, 500 whp on 100% E85.
• Stage 2.5 v2 (3.9 LPM): Single Walbro 535. Up to 650 whp on pump gas, 550 whp on 100% E85.

Both ratings are per Precision Raceworks and assume the Precision Raceworks In-Tank Fuel Filter & Regulator, described below, is installed alongside the pump.

How This Differs From the Modular Pump

This pump is not upgradeable. Precision Raceworks does not offer a pump module that converts this unit to a higher stage later, so it is best suited to owners who have settled on a specific horsepower target. Owners who anticipate raising their power goals in the future should look at the Precision Raceworks Bucketed Performance Fuel Pump for BMW E9x/E8x instead, which shares this platform's Stage 2 and 2.5 v2 options and adds Stage 3 through Stage 4 as later upgrade modules.

Required for Rated Performance

To reach the whp figures listed above, Precision Raceworks requires pairing this pump with the Precision Raceworks In-Tank Fuel Filter & Regulator (V2), sold separately.

Ownership Notes

• Some European-spec vehicles may require reusing the original top hat due to differences in factory fuel-system hardware.
• No lock ring tool is included with either stage.

Product Specifications

• Brand: Precision Raceworks

Frequently Asked Questions

Can I upgrade this pump to a higher stage later?
No. This is a fixed-stage design with no upgrade module available. If you want the option to grow into a higher stage later, choose the modular Bucketed Performance Fuel Pump instead.

Do I need the In-Tank Fuel Filter & Regulator to use this pump?
You can run the pump without it, but Precision Raceworks' rated whp figures for both stages assume it is installed. Add the In-Tank Fuel Filter & Regulator (V2) to reach the advertised numbers.

Is this pump E85 compatible?
Yes, both stages are 100% E85 compliant; use the E85 rating above when running ethanol blends.

Which stage should I pick?
Choose the stage rated above your target horsepower with some margin. If you are unsure which stage fits your build, contact your BMP Tuning rep.
