Hey Peter!

The dark green of the MB Sturgis Propane Pigtail w/ Back Check # 100473-24-MBS is what you want since this pigtail is rated for up to 450,000 Btu per hour.

What color is the ACME connector on your current pigtail?

Dark Green. I just want to be sure that I'm using the correct hose.

@Peter Dark green is the one! Does your regulator have the adapters installed where the pigtails connect to it? If it does, you'll need the Pigtail Hose # 100575-24-MBS with the inverted flare end on it instead.
