Six Pack Braided Fuel Line

Our Six Pack braided fuel line kit is designed for the performance enthusiast in mind.  This kit transforms you Six Pack into a fuel drinking machine, and is no longer limited by the 5/16" factory lines.  When building Six Pack engines for performance use we had found the factory lines to be a restriction.  Our new kit now converts everything to -6 AN line (3/8").  Not only is this line larger but it also seals great and is flexible (no more leaky lines!!).  We have also developed a new lower line kit that completes everything to the pump.  Our lower line kit also features a -6 AN filter with a Stainless Steele 40 micron filter.  The filter is re-useable and keeps the fuel to the carbs clean!

Upper SP line kit with gauge $150

Lower SP line kit with filter $75
