Description:
The biggest problem in increasing horsepower on the factory Subaru Boxxer engine is the fuel delivery. The factory system runs the fuel in series which tends to cause certain cylinders to obtain less fuel. In higher boost applications, these cylinders can lean out dangerously causing the motor to fail. The Agency Power Subaru Fuel Rail kit features -6 lines which are nylon coated in either red or blue. The lines feature AN fittings for a secure fit guarantying you will never have any leak issues. The new distribution block is mounted to the pitch stop mount under the top mount intercooler or front mount intercooler piping. Equal length line runs to each fuel rail to ensure proper fuel distribution for even the most powerful cars on the road. The new rail design features a 2 piece system that bolts in place of your factory unit. The rails seat securely on the injectors with the proper angle for the best and most precise spray pattern. The factory fuel pressure regular then is bolted to the distribution block where the return line runs to the fuel filter. Each distribution block features a 1/8 inch NPT brass fitting to run an external fuel pressure gauge. All 3 pieces are precision machined CNC 6061 aluminum. They have then been sand blasted and anodized in either red or blue for a smooth show finish. Each distribution block features the AP logo laser engraved. All fuel rail kits include the hardware and bracket for safe mounting. Only top feed injectors, such as the factory injectors, work with this kit.

Agency Power offers a multitude of engine, brake, and suspension parts that will help you achieve your vehicle's full potential.
Q: What do fuel rails do? Why buy fuel rails?
A: Fuel rails are designed to keep pressurized fuel flowing to the injectors. When high performance motors are built and the fuel pressure is increased, sometimes the standard bore on the fuel rail is too small, restricting fuel flow to the injectors and causing your car to lean out.
Q: Are fuel rails sold individually?
A: Fuel rails are sold individually unless otherwise noted.
Q: How do you install fuel rails?
A: Fuel rails are installed by removing the injectors and fuel pressure regulator from your factory rail. The factory fuel rail is then removed and the new unit is installed in its place. Specialty tools are needed to remove the fittings on your standard rail and to install new fittings into the new fuel rail. This job should be left to the pros if you've never done a fuel rail before.
