DeatschWerks FPHWK – Hardwire Fuel Pump Upgrade Kit

Why hard-wiring matters

Factory wiring often suffers voltage drop after years of use, so the fuel pump never reaches its advertised flow. A hardwire kit feeds direct power from the battery, eliminating losses and unlocking full pump performance under high load.

Key Features

• Complete plug-and-play package – power and ground leads, relay, fuse, socket and terminals in one box.

• 40 A relay & 30 A fuse – ample headroom for pumps above 340 LPH; built-in circuit protection.

• Broad compatibility – pairs perfectly with DW301, DW400 and other high-flow aftermarket pumps.

• Step-by-step instructions – simplifies installation even on older vehicles.
