We had previously installed the fuel line from the engine driven pump to the metering box. I will simply replace that with two shorter ones to get the Fuel Flow Sensor in line.
I had to learn about making fuel lines as well as order parts.
After surfing the web on Sunday, I decided to upgrade the oil cooler. The bigger one will fit on the baffle, simplifying the firewall real estate. Once it arrives, I will order the oil hoses.
This stuff is expensive. A typical hose will cost around $100. I ordered parts for 4. And, I ordered special tools to get a good assembly. Airplanes!
