Today I roughed in the 1/4" Fuel Return Line that runs down from the engine Fuel Pump through the Pylon to the Barbed Insert on the top of the Fuel Tank and also the 3/8" Fuel Inlet Line that runs down from the "front" of the engine through the Pylon to the Fuel Shut-off Valve located inside the arch of the Turtle Deck. I put "front" in quotes because I have yet to figure out how the Fuel Inlet Line gets the final two feet or so to the Fuel Pump. My rebuilt Rotax 912 did not come with the Fuel Line in that area that the Searey manual seems to be saying should be there.
