The short propane hose from the changeover valve to the tank on the passenger side of our Cyclone is leaking from the rear of the knob. When I plug in the part number listed on the tag at the Fairview Fittings site, I get a range of products that are close, but based on the description, none of them have the right-angle fitting like the one I'm replacing... any clue on how to order the exact replacement hose with the right-angle fitting? Thanks!
