RE: REMOTE FUEL FILL VALVE
The pressure line can stay connected and the fuel will just run out the muffler when filled. Some clubs with grass fields require a catch can. John uses the split line and has it come out of the cowl or fuse at some point and makes the set up easy and fool proof. It's just the main line and is split then held together with a piece of copper or brass tube. When John comes on I'm sure he will post some photos for you. One of the better ways to do it and nothing to ever go wrong.
