I have a Top Tier system and love it, but I've always had significant gas leakage from my black pipe joints. This is because the propane hose from the black pipe to the burner is so short that I can't crank the black pipe all the way tight, or else the fitting I have to connect to on the black pipe is a few inches too far away to reach. That is, looking down on the black pipe, I have to have the fitting at a location within a 20 degree slice of that circle in order to get the propane hose to connect.
I am reconfiguring my stand so this seems like a good time to fix that problem. It looks like I could buy a propane hose with 3/8 inch flare fittings from eBay, and then use a male/female adapter on one end of that to make that work.
However, before purchasing something at random that may not work, I was hoping to pick someone's brain about how to do this. I've seen pictures of people's TopTier stands with yellow propane flex hose instead of the propane hose that came with the system. If you're one of those people, I would appreciate knowing what kind of hose that is and where you bought it. Thanks!
