Overview

The DeatschWerks DW400 Pump Module + Return Kit with SS PTFE by DeatschWerks is engineered to maximize flow at higher pressures with an extremely flat flow curve. It features a composite impeller, encapsulated armature, carbon commutators, and brushes, along with PTFE fuel lines for methanol and e100 compatibility. This design allows for tighter radius turns and zero fuel vapor permeability, leading to a longer life in high-heat and high-pressure conditions. The kit includes the complete module with a pre-installed DW400, a fuel pressure gauge, a DWR1000 Adjustable Fuel Pressure Regulator, various AN to EFI quick connect adapters, O-ring boss to AN adapters, a 10 Micron In-line Fuel Filter Kit, 6AN Braided Stainless AN Hose, and 12 6AN Swivel Hose Ends.
