A week or so ago I posted that the hoses/fittings on the LP tanks should be checked for leaks as mine had developed one. I contacted the manufacturer of the hoses, Marshall Brass who has made valves, lines and other things in the RV line for many years. I was contacted by a rep from the company today and was asked to send the hose/fittings to them via pre-paid shipping. Understandingly, they want to inspect the items to see if there is a manufacturing defect or faulty crimping of the hose. I informed them by letter the reason I was concerned and they agreed. I will try and keep the forum informed as I receive any information from them. In the meantime, please inspect yours for leaks. It is too late after the fact.
