I need some help. We have a NTU 2010 Coleman Utah, and we are having trouble with the outdoor grill. The curbside hookup runs at 16 psi, and when we open the line to the grill it immediately starts leaking at the connection to the grill. We were under the impression that the grill and hose were original parts of the trailer, but when we looked closer the hose said "1/2 psi max." Clearly a 1/2 psi hose has no business being connected to a 16 psi line. So here's my question - is this a low pressure stove that a PO mistakenly purchased for this high pressure line? Or is this a high pressure stove and someone just had the wrong hose? The stove itself has a quick connect fitting, which leads me to think it is meant for low pressure. Is there such a thing as a high pressure quick connect for these curbside grills? Pictures attached show the grill, including the connection on the grill itself, and the curbside hookup on the PUP.
