Whenever we need to pass a fuel line, electric cable, or throttle cable from the inside of our cabin to the engine compartment, we need to make a breach in the firewall. Cutting the hole to route these items is the easy part - how to properly seal the opening is the tougher step!
Because the firewall of our homebuilt aircraft is designed to protect the occupants from potential leaking exhaust carbon monoxide and smoke from an engine fire, we must consider carefully how best to make these holes so they properly maintain the firewall's intended protection.
Our Tip this week presents some of the off the shelf components that can be used to properly route your fuel, electric and control cables through the firewall and still maintain the fire and gas rating that the firewall intended.The components in the video were supplied by Aircraft Spruce.
