I replaced mine with a precision and about 2 weeks later the check valve went. I just put a check valve on the line. and left it. It runs fine this way.

As long as I have good running pressure, I’m not dropping my tank again. I don’t have help to pull the bed and I was informed I couldn’t use the tree and straps to lift it haha!

unfortunately I believe the shuttle valve inside the fdm is not actuating. I’ve got too much pressure at the rail.
