RE: Great Planes Extra 300 GP/EP
Ttaylor63 -
I didn't mount a fuel plug on the cowl. I just added a bit of length to the fuel lines and pulled it back on top of the fuel tank. My tank and the fuel line are held in place with Velcro(TM) and I haven't had an issue since. Take a peek at the image...the fuel plug I use is the Great Planes Easy Fueler Valve. Link below:
