Snow Fuel Rail Kit – Return Style System for LS3 Manifold w/ 34mm Injector Height (1999–2006 Silverado 1500/2500 V8 Gas) SNF-34343
If you're in the market for flimsy fuel rails with weak brackets and a tendency to leak—this isn't the kit for you. But if you're after precision, durability, and top-tier performance, Snow Performance delivers exactly that.
Proudly made in the USA, Snow Fuel Rails are crafted from premium materials and CNC-machined for exact fitment. Each rail is finished in black anodizing for a clean look and long-lasting corrosion resistance.
This kit includes stainless steel brackets designed for factory LS3-style injectors (34mm height). For alternate injector setups, Snow offers optional brackets and spacers (sold separately) to fit a wide range of LS and truck intake manifolds. The included brackets are engineered to hold firm under high fuel pressure, ensuring leak-free operation.
Built to handle serious fuel flow, these rails feature 8AN ORB ports at both ends for unrestricted delivery. Each rail also includes dual 1/8-NPT ports for easy integration of sensors, gauges, or nitrous feed lines—no extra adapters required.

- Two Billet Aluminum Fuel Rails
- Four 1/8-NPT Port Plugs
