I'm finally finishing an Ace T-34 that I started 17 years ago. I've never built a cowled plane before and am wondering how to fuel the plane without taking of the cowl. It has a 2-line system. Is there some kind of fitting or what have you to put in the fuel line to run outside the cowl? Don't really want to tear into the fuel system as I'm ready to cover and the tank is not accesible without removing sheeting. Thanks in advance. Tom
