Brief Description: Installing the engine sensor manifold
I drilled the firewall passthroughs for the engine system sensor manifold. The top bolt hole goes through an existing firewall rivet position. Once I drilled it out and mounted the manifold with a bolt, I used the lower hole to match-drill the lower bolt hole. Installed platenuts to the aft side of the firewall, installed plugs and 45 and 90 degree elbows, then re-mounted it all permanently to the firewall.
