Product Description

The DeatschWerks FPHWK-10-DP is a universal dual-pump hardwire kit engineered for enthusiasts running twin fuel pump setups. By hardwiring pumps directly to the battery, this kit eliminates voltage drop issues associated with aged OE harnesses, ensuring stable power delivery up to 40 A per pump. Ideal for boosted builds, high-horsepower projects, or dual-pump fuel systems.

Installation is straightforward: route the heavy-gauge power and ground wires, plug the OE pump trigger wire into the factory side of the relay, and secure the battery connections. A nylon loom protects wiring from abrasion, while dual fuses and relays ensure safety and reliability. This non-vehicle-specific kit fits virtually any application where direct battery wiring is needed.
