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

Part #: PRW - PWFR01. These fuel rails stand out from the competition. They are genuine 'machined from the solid' billet rails, not cheap extrusions masquerading as billet. With large '-8' fittings, they can handle high - capacity fuel systems with new - generation large - capacity fuel injectors. The twin top and single end entry/exit design can be configured as you need. They fit 11mm or 13mm diameter injectors and come with two - 8 plugs and mounting hardware for stock or Process West Billet TGVs.

Using these fuel rails is straightforward. First, make sure you have the right size injectors (11mm or 13mm). Attach the fuel rails using the provided mounting hardware to either your stock or Process West Billet TGVs. Connect the fuel system using the large '-8' fittings. When it comes to maintenance, regularly check the connections to ensure there are no leaks. If you notice any signs of wear or damage, replace the parts as soon as possible. Always follow the manufacturer's guidelines for your fuel system and vehicle. Avoid over - tightening the fittings as it may cause damage. Keep the fuel rails clean to ensure optimal performance.
