BMW E9X & E8X Spool Stage 2 Bucketless Low Pressure Fuel Pump

The Spool Stage 2 bucketless low pressure fuel pump for the BMW E9X and E8X more than doubles stock flow and is ready for full E85.

Why you need it

A weak in-tank pump starves the high pressure pump once you add power or ethanol. This drop-in pump flows more than twice the stock pump, runs 100% E85, needs no major assembly, and comes with a new OEM injection-molded pump connector. It is modular, so it can snap up to a Stage 3 setup later.

Good to know

The optional Pro fuel lines are 6AN nylon and stainless braided with a PTFE core, CNC-machined aluminum fittings, a burst rating over 10,000 psi and a 450 F working temperature. Pick no line upgrade if you are keeping your current lines. The ethanol sensor versions do not include the sensor itself.
