The Mason lines are great fuel lines!

I found it easiest to take out the airbox and intake system to install the new fuel lines. Sounds like a lot of work, but it's not. It allows you to address other things such as replacing old cracked vacuum lines, tackle the "triangle of death" which was super simple btw, sending all of your clamps and hardware to be zinc plated, and replace the intake manifold gaskets. With the manifolds out, you can replace all of the wear items, and install the Mason fuel lines directly.

It's a lot easier than struggling trying to wrap your arms around and under the manifolds while bent over at a bad angle wrecking your lower back.

Pro tip: If you take out you manifolds, remember to plug the metal return fuel line (back left of engine underneath the cruise control unit) very well as the fuel vapor in the tank and lines will cause pressure build up leading to fuel shooting out of the return line and spill everywhere. Happened to me - 2 pints of fuel drained onto the floor of my garage and it stank for weeks.
