P&L Motorsports offers a unique service to 2008+ STIs. For those who lack the tools, time, or know-how — we are more than happy to help. We properly modify and reinforce the factory fuel cage for the 2008+ STI, and install a high quality Walbro 400lph that is compatible with E85 fuel pump. We then re-assemble and package your housing back up for shipment.
There is a one to two day turn around on pump modifications, from receipt of your factory pump and housing. As an option, we can also supply a core exchange or new housing modified and ready to go, for zero down time. You will be charged the full amount ($724.95/$999.95) but refunded the difference once we have confirmed functionality of your unit.
Please Note: The Walbro 485 pump requires an large electrical draw to power itself. Due to this, it is common to short out the factory electrical harness which normally powers the fuel pump. P&L highly suggests hard wiring the 485 pump directly from the battery. We can provide a pre-made direct wire kit for your convenience for an additional cost upon request.
