I began finishing up the area under the fuel cover that sits on the floor between the pilots feet. Earlier I had ran the fuel lines and wiring through this area and now wanted to finish things up. First I trimmed the cover to allow the wiring harness to pass through. I then got some polyeurethane blocks and sandwiched the fuel supply and return lines so that they will not come in contact with the floor or cover. I also secured all wiring and covered any wires with plastic tubing at any possible shafe points,
