The fuel line kit included 25 feet of #6 push-lock hose, but it wasn’t enough for us to run both supply and return lines. We connected the pressure line from the fuel pump to the factory steel line while using the hose on the return side. Unless you have the muscles of an Olympic weightlifter, you’ll need to warm the hose end with a heat gun before pressing in the fitting. It helps to clamp the fitting in a padded bench vise and push the hose over it. Like the fuel pump kit, these parts are included in the Master kit and also sold separately (PN 307600, $150).
