Whipple High Flow Fuel Rails - Accepts -8an fittings (2011-2017 Mustang GT with Gen 5 Whipple) - WFP-MU15RAIL-8

Need more fuel for your Gen 5 3.0L Whipple Setup? The bottleneck might be the -6an fittings in the fuel rails originally included in your kit.

Upgrade to these -8an fuel rails (originally included in the Cobra Jet kits) to remove that bottle neck.

Make sure to add some 8an fittings to your order in the options.  Your old 6an fittings will not fit anymore.
