Process West Billet Fuel Rails Black Subaru WRX 2002-2014 / STI 2007-2018

Part #: PRW - PWFR01B. These fuel rails stand out from the competition. They're truly machined from solid billet, not just cheap extrusions masquerading as billet. With support for massive '-8' fittings, they can easily handle high - capacity fuel systems with new - generation large - capacity fuel injectors. The twin top and single end entry/exit ports can be configured as needed. Available for 11mm or 13mm diameter injectors, they come with two - 8 plugs and mounting hardware for both stock and Process West Billet TGV's.

Using these fuel rails is easy. First, make sure you have the right tools handy. Check if your fuel injectors are 11mm or 13mm in diameter and select the appropriate fuel rails. Install the two - 8 plugs that come with the set. Then, use the provided mounting hardware to attach the rails to either your stock parts or Process West Billet TGV's. When installing, be gentle to avoid any damage. As for maintenance, regularly check the fittings to ensure they're tight and there are no leaks. If you notice any issues, have them inspected by a professional. Also, keep the fuel rails clean to extend their lifespan.
