Spool LPFP in-tank pump, BMW E9x / E8x N54 engines

Spool Performance fuel pumps for BMW models

Spool LPFP in-tank pump kit, BMW 135i and 335i N54 models (E8x E9x)
Known weak point when tuning BMW N54 engine, can be found from the original in-tank LPFP pump which isn’t up for any tuning stages above basic “Stage1” tunes. To maintain a safe line pressure that is able to feed the HPFP high pressure pump without line pressure crashes, upgrade your tank unit with modular Spool LPFP kit.

Choose one of the two stages, as the name suggests Stage3 is often preferred when running a big hybrid turbo or full E85 build.

• Choose Stage2 or 3, modular design allows you to upgrade later on as well
• Model specific kit, makes the installation easier.
• Fully E85 compatible
• Available with optional AN6 fuel line from tank to HPFP

Optional fuel line can be bought with option for ethanol content sensor. Sensor not included.
