The Nuke Performance Fuel Rail is thought to be the highest flow rate rail on the market. This version is compatible with Volkswagen VR6 engines. The body and all components are CNC-machined from 6082 aluminum alloy. All the fittings has Viton O-rings for long lasting operation. The fuel rail has an anodized finish for long lasting function and a corrosion free appearance. Mounting brackets sold separately. If space is an issue we recommend you to use Nuke's Banjo-type fitting, with oversized internal dimension for minimum cavitation.
