Tank vents

Post by jim_geo »

Standard fuel tank vent lines are shown in the drawings as pointing straight up at the lower front fuse longeron. When I followed the drawing I found it nearly impossible to jump the longeron and dip behind the rudder cable and then also be able to get a flare fitting on the end of the tubing that would make a connection, that I felt confident of, to the 90 degree AN fitting. It's a little bit cramped down there so I pointed the AN fittings forward and made a bit of a switch back on the tubes. It made it much easier to jump the longeron and make the desired bend behind the rudder cable and the tubing can stay tucked in close to the fuse wall.

I'm really struggling to figure out what I'm looking at here Jim... :? Is the fuse tipped on it's side? :oops:

Chad, My fuse has been on its side for awhile now. I'll be attaching the firewall recess today and putting it back upright today though. It’s certainly been easier to work on with it on its side than to be crawling around inside or reaching over the side.

Yes Dave I used most of those tools but probably not the screw driver. Actually those tools have pretty much been living there for the last month or so

Hi Jim
Nice job on the vent lines, i made mine a couple of months ago, i have worked with brake lines before and did manage to make them as per plans, but looking at yours i may remake them.
Cheers
