Pure Choice Motorsports offers the quickest way to connect the factory steel lines to your LT1 with a complete kit including everything you will need from the adapter fittings on the frame rail to push/connect fittings on the fuel rail. The kit includes 14 and 16mm metric O-ring-to -6 AN adapters (part No. 5090), fully assembled Teflon lined braided -6 line, and lastly a pair of Push-Connect-to -6 AN adapters. All of the parts appeared well engineered with obvious attention to detail. Both Pure Choice and Aeromotive stressed changes in fuel additives in 2002. If you don't use the appropriate fuel system components, the new fuels will eat right through the lines. Pure Choice addresses these issues with its Teflon braided line.
