Brief Description: Fuel Line Redo - Mid Cabin Fuel Lines
|
|
Proceeded with making new fuel lines from the left tank to value, fuel valve to fuel filter and filter to boost pump.
Initially I used garden wire, which I twisted to create a straight and sturdy wire to mock each fuel line. For each line, used the garden wire mock-up to bend the 3/8" aluminum line as needed. Though I created this mock line, I still ended up creating each 'actual' line multiple times before I got anything actually useful.
I drilled out the rivets for the filter cradle, as it became painfully obvious its current location was not going to work. The basic issue is the filter much be serviced on the annual condition inspection, so it must be installed in a way that is, well, serviceable. To maximum the space on the input and output sides of the filter, oriented the filter 45 degrees relative to the fuse.
Made the left tank to fuel value line - only required 2 tries
Made the fuel valve line to filter - required 3 tries.
Made the fuel filter to boost pump line - lost count on the attempts...
