The final drain line is from the Fuel Distributor (AKA spider… you’ll see why in a minute) which sends fuel to each cylinder.<\/p>\n

This one will be the trickiest since it will have to penetrate the plenum. First I looked through all my pictures of other IO-550N installations to see where those lines were routed.<\/p>\n

Here’s the engine as it sits now. The spider is the silver hockey puck with 6 small lines coming out (I guess it should be called an insect) which go to each cylinder. The drain fitting is on the bottom pointing towards the right.<\/p>\n

Here’s the drain line connected.<\/p>\n

I drilled a hole in the right deck of the baffle and put a grommet in it and then ran the drain line through it.<\/p>\n

\"\"<\/a><\/p>\n

And out the bottom.<\/p>\n

\"\"<\/a><\/p>\n

The line is then clamped to the engine mount near the oil cooler.<\/p>\n

\"\"<\/a><\/p>\n

Over to the firewall (I still have to put another clamp on the line at the firewall).<\/p>\n

\"\"<\/a><\/p>\n

And out the bottom of the fuselage just to the right of the fuel pump drains.<\/p>\n

Many builders put the flexible drain lines in firesleeve. I checked with my A&P and some references and determined that since the drain lines are non-pressurized and go overboard, it is not necessary to use firesleeve.<\/p>\n","protected":false},"excerpt":{"rendered":"
