BMW F10 550i N63 & N63TU Spool Stage 3 Low Pressure Fuel Pump DIY Kit

The Spool Stage 3 low pressure fuel pump DIY kit for the BMW F10 N63 adds a second in-tank pump so the low side keeps up on high-horsepower builds.

Why you need it

With upgraded high pressure pumps able to support far more direct injection fueling, the factory in-tank pump becomes the limit, especially on E85. This twin-pump design brings the second pump in at boost onset, giving almost double the flow of a stock pump and enough for over 1200 whp of low pressure fueling on any fuel.
