If you get the hoses fabricated, make sure they use hose fittings that are rated to the higher pressure as well as the hose. I had a low pressure hose with quick connect made for a portable oven (11" pressure) at a shop that sold and installed gas logs and high dollar kitchen ranges (Jenair type that even had grills in the top). I used it to connect the oven to the low pressure outside stove connection on my pop up. Asked them to make some high pressure hoses for me and they said they didn't have the fittings and the crimping equipment for them. Had to get them made at a welding supply shop. Make sure the hose is also rated to handle propane.
