1. The fuel line sides P4108 and P4109 can be installed. Note: you will need to make a cutout in one side to allow the fuel line to pass outside of the cover and into the firewall fitting. Which side you put it on, how large of a cutout will depend on where the fitting best fits for your engine choice.
2. View looking up and aft at the bottom forward fuselage showing the rivets installed for the fuel line cover. Heads are on the underside of the fuselage.
3. After the fuel line is installed, the top P4110 can be riveted in place.
