McLaren 720S, 750S, 765LT & GT Spool Stage 3 Low Pressure Fuel Pump Kit

The Spool Stage 3 low pressure fuel pump kit for the McLaren M840T 4.0 twin-turbo V8 keeps your OEM pump and adds a second one, so the low side keeps up on big power and E85.

Why you need it

The stock low pressure system starts to run out once you push past about 800 whp or switch to an E85-based blend. This kit converts the factory setup to twin pumps and supports up to 1500 whp of fueling, with the extra pump switched on by a Hobbs switch under boost.
