Motorsport-Grade Plumbing. Zero Compromises.

Most intake manifolds on the market come with a port injection rail but no fuel line, leaving the customer or shop to figure out their own option. But with there being limited options on the market for just a fuel line, we wanted to change that…

The RVNG S58 Full Port Injection Fuel Line Kit was made to support high-horsepower builds where reliability, flow, and serviceability matter just as much as performance. Designed specifically for S58 port injection setups, this kit eliminates the weak points of pieced-together fuel plumbing and replaces them with a true motorsport-grade solution.

Each kit features high-pressure PTFE-lined braided fuel hose, paired with CNC-machined motorsport fittings rated for ethanol, E85, and high-pressure fuel systems. Precision angled fittings ensure clean routing with no kinks, no interference, and proper clearance in tight engine bays—especially critical on turbo and manifold-heavy S58 builds.

To make installation and servicing effortless, the system incorporates quick-disconnect fittings, allowing fast removal and reinstallation without compromising sealing integrity. Every connection is designed to handle extreme heat, vibration, and pressure commonly seen in high-boost S58 applications.

This is not a universal fuel line set—this is a purpose-built, plug-and-play port injection fuel solution developed to meet the demands of serious street, track, and race builds.
