RE: I NEED YOUR HELP
The easiest set up for you may be to run a 2 line set up...the vent line will go to your muffler, and the fuel line could be routed out the bottom or side of the cowl in an inconspicious place. Use a small piece of brass tube and bend a small "U" shaped piece. Use this piece to splice the fuel line, so that you can unhook the fuel pick up line outside of the cowl to fuel the plane. Just watch for fuel running out of your mufler when you fill it up, then hook your lines back together. Good luck with it! -Craig
