Need help with propane pressure issue
I have a 2007 Keystone 5th wheel RV that has dual 30 lb propane tanks mounted in the front corners of the trailer. I've been having issues getting proper pressure out of the right hand propane tank. Left hand tank works well. When using the right hand tank, I get propane to all appliances, put at lower than normal pressure. The flame on the stove top is only about 1/3 of normal on this tank. Had different propane tanks in this location with the same issue. The propane routes from this right hand tank into a rubber pigtail that is then connected to a hard line. At the other end of the hardline is another rubber line that connects the hard line to the manual tank selector switch. I replaced the rubber pigtail at the right hand tank and that made the problem better for a while, but the issue has returned. Is there a way to test the pigtail to determine if my new pigtail is defective? Should I replace the other soft line in this connection? Could my problem be in the manual selector switch? Getting tired of having to carry the right tank to the left side when the left tanks runs out.
