My grill was designed to go in a low pressure line. Helps keep the cost down, I guess. I could have purchased an accessory hose with regulator, but I tapped into my low pressure line where the flexible hose connected to the copper pipe on the trailer and added a quick disconnect fitting. My grill came with a 3' hose and I bought a 10' extension. After I got low pressure and high pressure QD fittings all sorted out (CW sold me a high pressure QD that was marked low pressure) everything worked fine.
