Upgrade your fuel system with the Precision Raceworks AN6 fuel line kit, designed as a direct replacement for your fuel pump in an aftermarket MPI system. Don't have an aftermarket MPI? Then you'll need an additional fitting (-6 Male Flare to 5/16" hose barb) to connect the rubber OEM line.

Features:
High Quality Construction: All connections are designed and manufactured in-house from 6061 aluminum and then anodized for 100% E85 compatibility. The fuel line kit is made of PTFE with a stainless steel and nylon jacket, ideal for high-end E85 applications.
Stage 3 Fuel Line Kit: Perfect for replacing restrictive factory fuel lines, this kit includes everything you need to rewire the lines from the tank to the high pressure pump. With a full AN6 line, this kit can support over 750whp when paired with the correct fuel pump.

Optimization and Reliability:
Even if you're running just under 750whp, this upgrade provides the extra fuel you need for Stage 3 or 3.5 pumps. Tuners worldwide recommend this fuel line kit for optimal performance and reliability.

This upgrade is essential for serious tuners who want to get the most out of their engine without compromising reliability, especially when using E85 fuel.
