The Precision Raceworks AN6 Fuel Line Upgrade options are a direct replacement for the fuel line from the fuel pump to the MPI system. All connections are designed in-house and machined from 6061 aluminium, then anodised to meet 10% E85 compliance. The fuel line used by Precision Raceworks is a smooth-bore PTFE line with both stainless steel and nylon jackets, used in high-end E85 applications built all over the world. The stage 3 fuel line kit is a great option for anyone looking to remove the restrictive factory fuel line. This line kit comes with everything needed to replace the fuel line from the tank to your Precision Raceworks MPI kit. With a full-bore AN6line,e this line can support 750 whp when paired with the proper fuel pump. Not making 750 whp but falling just short of having enough fuel for your stage 3 or stage 3.5 fuel pump? THIS LINE IS FOR YOU! Tuners didn’t believe the chart below when we first published the data, but it didn’t take long for tuners around the world to tell every customer to upgrade to the Precision Raceworks fuel lines.
