The Nuke Performance fuel rail for Volvo engines is thought to be the highest flow rate rail on the market. This version is compatible with Volvo's B23/230 4 cylinder 8 or 16 valve engines and includes the 99-01-101 bolt-on kit. 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. Ships with 2x 3/4 UNF AN-8 fittings, 1x 1/4 G plug and stainless steel mounting brackets + hardware. If space is an issue we recommend you to use Nuke's Banjo-type fitting, with oversized internal dimension for minimum cavitation. For easy installation use Nuke 99-01-101 bolt-on kit.
