Whether you're on the dyno getting a tune, sending it on the track, or just heading out to get the groceries, our kit ensures your upgraded fuel pump can keep up with your engine's demands.

The Plug-and-Play Solution For Your Fuel Pump Upgrade
Anyone can install the iWire Fuel Pump Hardwire Kit with only standard tools and a little time. We include step-by-step instructions and all the components to make this kit, dare we say, enjoyable.

Don't Run Out of Fuel. Maximize Flow No Matter Which Pump or Hanger
The iWire Hardwire Kit improves the fuel system electronics to ensure your engine gets the fuel it needs. The factory FPC steps down the voltage from 14v to 12v, so we designed our kit to pull power directly from the battery to maximize your pump's capabilities. We increased the wire size to handle a larger pump's increased electrical current and beefed up the grounding circuit to keep up with the heightened demand. We aim to bridge the gap between the inefficiency of your stock wiring and the ideal conditions of the fuel pump testing lab.

Stud Bypass for OEM Hangers
The most common failure of the fuel pump or fuel pump controller is the connector overheating and melting. Our Stud Bypass Kit moves the power and ground wires out of the stock connector to eliminate any concerns of terminal, terminal failure.

Don't Cut any Wires for Your Radium Hanger Install.
We designed our Hardwire Kit to work specifically with your Radium Hanger for a seamless installation. We have addressed potential concerns from an upgraded pump and the connection differences between Radium and Subaru. Our harness adapter makes connecting the Radium hanger painless, and you'll also have the confidence the wiring can handle anything you throw at it with its large gauge wire and easy-to-follow installation instructions.

The Fuel Pump Controller (FPC) is Your Secret to Horsepower and Drivability
iWire designed the kit so that the FPC stays in the system to retain the pump's low/medium/high settings. With this feature maintained, the FPC can deliver the correct amount of fuel under any condition and shut it off if there is a problem. Other "hardwire kits" remove the FPC, which causes the fuel pump to run at maximum speed constantly. With the intermediate settings, your pump will work efficiently in all conditions, like bumper-to-bumper traffic, which does not require as much fuel. Another byproduct of the pump working too hard is increased fuel temperatures, reducing horsepower. Worst of all, the pump may stay on if there is an accident or fire.

Expandable for Future Fuel System Upgrades
The base kit works with pumps of any size. For example, if you switch from an AEM 340 to a Walbro 450, there will be no issues. Just reach out to us to reconfigure your kit. If you decide to go with a Radium hanger in the future (single or double pump), we have add-on packages to your current setup to make those upgrades a breeze.
