Most of the kitchen fausets now have long hoses already attached. The RV fausets are really cheap. My DW picked out a real nice kitchen fauset at Lowes. It has the fancy fauset head that pulls out. No problem installing it. Very nice quality and all parts will be available. Next I will change out bathroom fauset. Trying to repair the RV cheap fauset is a waste of time. If you are going to just attempt a repair take that fitting loose and install a new washer if you can find one. Doubt just tightening will stop the leak.
