We've designed a dual pump hanger for the 09+ Subaru WRX STI and Legacy. This kit will include everything you need to mount (2) walbro 255hp pumps inside the tank. We have tested this setup up to 900+hp in many other vehicles. No more sumping the tank or modifying the tank to make power. This is the last fuel system that you will need. ** we offer complete kits that include lines to the front of the vehicle and back as well. Please contact us for more details.
