I replaced the fuel lines with Earls. Before the line gets to the fuel rail I used the fuel test port from Pegasus.

You also need the fittings recommended. It goes in very easily and takes no real-estate.

I also zip-tied a piece of 3/8" rubber hose to the roll cage so it can be whipped out and connected to this port. The tech guys loved that!
