When upgrading the fuel injectors, lines and fuel rails on your 2002-2007 Subaru WRX or 2007 STI, it's necessary to address the relocation of the fuel pressure regulator. Since the regulator is attached to the OEM fuel rail, replacing the rails eliminates the mounting point for the regulator. IAG’s Fuel Pressure Regulator (FPR) Adapter is designed to accommodate fuel system upgrades by allowing the stock FPR to be remotely mounted. This innovative solution ensures seamless integration of upgraded fuel system components without compromising performance or reliability.

The IAG Performance Fuel Pressure Regulator Adapter retains the stock fuel line outlet, converting the o-ring inlet to a ⅜ inch outer diameter hose barb with a raised lip to ensure a secure seal. With a convenient ¼ inch hole for universal mounting in the engine bay using a single 6mm bolt, it provides a safe and out-of-the-way solution when upgrading to high-flowing fuel systems like the V3 Top Feed Billet Aluminum Fuel Rails.

IAG’s Fuel Pressure Regulator Adapter is precision machined from a single piece of lightweight and durable 6061 aluminum, ensuring it can withstand the heat and harsh conditions under the hood while retaining a seamless fitment to the OEM FPR. The adapter comes with zinc-coated steel hardware, known for its durability and strength, ensuring a secure hold for the fuel pressure regulator adapter.

The IAG Performance Fuel Pressure Regulator Adapter makes installation of your FPR easier than ever with its universal mounting design. If you're tackling the mechanical work to upgrade your fuel system with larger lines, injectors, adaptors, and high-flowing fuel rails, this adapter requires only a single bolt to mount, making it the simplest part of your fuel system upgrades.
