iWire Fuel Pump Controller Hardwire Kit for Radium Hangers - Single Pump

If you are sitting at a stoplight, the fuel demand is much less than full throttle at the track. Unlike other "hardwire kits," our kit keeps the FPC in place so the pump can deliver the appropriate amount of fuel for what the engine needs in any scenario. When you remove the FPC from the system, the pump runs at full blast, which leads to increased fuel temps (decreased horsepower) and overrunning the fuel pressure regulator (decreased drivability). Running a kit that removes the FPC will create a serious challenge for your tuner to deliver you a smooth-revving car that also makes the most power possible. 

Why Can’t I Just Put My Upgraded Pump in the Stock Fuel Hanger? 

The fuel level gauge might be tricking you because it displays the average amount of fuel between the two saddles. Suppose you put an upgraded pump in a stock hanger. In that case, you likely have most of the fuel on the wrong side of the saddle (non-pump side) because the siphon that equalizes this out isn’t working correctly. Radium has created an improved hanger that makes sure that fuel gets to the pump side of the tank and directs the fuel to fill up the basket that holds the pump to reduce the chances of fuel starvation.

Don’t Cut any Wires for Your Radium Hanger Install

We designed our Hardwire Kit to work specifically with your Radium Hanger to make for a seamless installation. We have addressed any 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. 

You’ll Probably Need That Second Pump at Some Point

With our kit, you are prepped and ready at any point to add in that second pump when it’s time to go for more horsepower. Simply add on our Radium Double Pump Add-On Kit, and you’ll have as much fuel as you could possibly need.
