Fabricated the angle per the plans to provide stiffness to the firewall where the pressure transducer manifold bolts in place.
Installed the 45° and 90° elbows for the oil pressure and fuel pressure respectively to in the pressure sensor manifold using Permatex #2 to seal the NPT threads. Installed NPT plugs in the unused ports in the manifold (except for the top set of ports which are not used). Bolted the pressure manifold and back up angle in place on the firewall. Installed and torqued the oil pressure hose fuel pressure hose on the pressure sensor manifold
Drilled two holes in the firewall and mounted the manifold pressure sensor in place.
Designed and fabricated a custom support to mount the GPS antenna (for the IFD-440) to the firewall.
