You do fantastic work I am really impressed. Thanks for the great pictures! What size tank are you using and will you need a pump to get the fuel from the tank to the engine. This is my first gas engine installation and some details on the fuel consumption, etc I do not have. I finally, got the Evolution 45GX2 engine installed. It is not as clean an installion as yours and it has been a challenge with getting the cowling and all to fit. I need to beef up the back side of the firewall a bit more with some trianglar pieces and epoxy. What do you use for fuel proofing? I was going to use some polyurhene. You are a great help.
