Autotech's new billet aluminum fuel rail for Mk4 1.8T models represents yet another first in VW tuning. The SportTuned Fuel Rail is the first one-piece VW rail to integrate the pressure regulator. It is a purpose-built 1.8T rail, machined from billet 6061-T6 aluminum, not made from a universal extrusion like others on the market. There's no other parts to buy in order to make it work in your VW - no remote regulator, no regulator mount, no hose. A standard, factory pressure regulator fits directly into our rail and clips in using the factory clip and o-rings. The integrated regulator makes for a clean installation without extra fuel lines to run. The SportTuned Fuel Rail is available in your choice of two finishes: fully polished or bright red anodized. Each comes with black anodized hose fittings and ARP stainless mounting bolts. Made in USA.
