Evo 123 - DeatschWerks - DW420 420 LPH In-Tank Fuel Pump (AWD Setup)
DeatschWerks DW420 420 LPH in-tank fuel pump — Evo 1/2/3 AWD hanger
This is the pump for the build that has already outgrown a 340. Ethanol needs roughly 30% more volume than gasoline to make the same power, so a full E85 tune on a large-turbo 4G63 can put a mid-range pump on its limit at exactly the wrong moment. The DW420 is the highest-flowing standard-fitment in-tank pump in the DeatschWerks range, which means you can chase that fuel demand from a single unit in the factory hanger instead of plumbing in an external pump and surge tank. One thing to budget for alongside it: a 10-gauge hardwire kit is strongly recommended so the pump actually sees the voltage it needs.
