Every long distance plane needs relief tubes or there is no point in having a lot of fuel on board. I’ve decided to put tubes down each leg. One running to the front for the pilot and the other for the GIB (Guy or Girl In Back). I feel separate facilities may eradicate any possible future ‘leaving the seat up’ issues.

I’ve used 3/8″ or 10mm OD tubing. Just PVC and I’m securing them at the rear midpoint of the gear bow. You might argue that it would be easier to put this tube first and the very small OD brake lines next. My thinking is that the brakes are critical, so they don’t get to sit on the very soft, cheap, low melting point plastic tube. They get secured to the hard gear leg and the relief tube goes on top of that.

I’ve taped (or gaffered) the tubes in place and then a little hot glue to keep them there.

As with the brake lines I’ve done a gaffa backing and then used dry micro to secure the tube.

After the top cured I used dry micro again and did the bottom of the tube. So we have gear leg, brake line and 3/8″ plastic tube all microed securely.  Now I’m ready to do the gear leg fairings.
