DeatschWerks Relays/Relay Kits FPHWK-10-HD

Get the most out of your DW high flow fuel pump by ensuring it gets the voltage it needs. Old, compromised OE wiring can limit the voltage your fuel pump receives. Our Heavy Duty hardwire kit features everything you need to safely, easily, and reliably wire your pump directly to your battery, ensuring no matter how hard you push your pump, your wiring will be up to the task. We especially recommend this kit for use in cars over 10 years old, cars making over 800whp, and cars which were originally not designed for high horsepower.
