Purchased new class A Dutch Star with Factory pickup. Had them install a propane line for gas grill connection from the unit built in tank. My prior unit had such a line, but it was high pressure off tank and used the regulator off the gas grill unit. Used an adapter hose to connect to the grill regulator having a typical 1lb disposable tank connection. The factory folks said by code they would have to install the line after the system regulator, which means low pressure. Now the grill won't work because (I think) the pressure is too low for the gas grill regulator to function. All my current hoses/connections need the gas grill regulator in place. Can I figure out how to eliminate the gas grill regulator and connect direct? Anyone know of a solution?
