Spool's Stage 3 adds a boost-activated secondary in-tank pump, roughly doubling low-pressure flow.\u003c\/p\u003e\n\u003ch3\u003eWhat it is\u003c\/h3\u003e\n\u003cp\u003eA twin-pump in-tank upgrade: the factory pump plus a second pump that switches on under boost — it ships with Spool's Hobbs (boost) switch for activation, so cruise stays factory-quiet and the system only ramps when you're on it. Spool rates it to support 1,200+ whp, and it's a complete drop-in replacement.\u003c\/p\u003e\n\u003ch3\u003eWhere it fits in the build\u003c\/h3\u003e\n\u003cp\u003eLow-pressure (in-tank) side; it pairs with an upgraded high-pressure (DI) pump so the HPFP is never starved.
