Well the rain let up a bit. Went out and started with just the injector return test. Run the truck at idle, use Insite to run the High Pressure Fuel Leakage test. When you get a steady stream and the pressure stabilizes, move your drain line over to a graduated cylinder. Count off 60 seconds and measure how much drained out. Anything over 200ml and you have leaking injector(s).

I counted off the 60 seconds, I had collected 1300ml.

On to the isolation test which resulted in every injector but #6 leaking. Looks like I'm getting 6 new injectors and connectors.
