Already have one of the Lethal Performance or DivisionX 850-2000 rwhp fuel systems on your 2011-2014 Mustang GT / Boss 302 or 2013-2014 Shelby GT500 and want to upgrade from the standard push-lock hose to the PTFE hoses? Well then this kit is for you! This kit comes with all the lines and fittings needed to replace the push-lock hose and fittings on your car, and it's already completely assembled, just run the lines and thread them onto the current AN fittings at the hat, filter, regulator and rails. This is the only hose kit that guarantees no fuel smell to weep from the lines and fittings.
