Sorry for sounding like I should be on the short bus but....
Does anyone have a diagram of how to setup a GP Easy Fueler valve? I've read through many of the threads here and have an idea, but I always need a visual; specifically, the 3rd (fill) line from the tank. What is this used for and why do some people plug it?
With the cowl on the plane covering up the tubing, how can one tell when the fuel tank is full other than watching fuel come out of your muffler (a waste)? Should it be installed on the cowl or on the fuse? Trying to install on GP Venus 40.....
