Brief Description: Revised fuel vent plumbing: part 2
The connection to the lower sight gauge tank fitting is far more straightforward and only requires one simple 90 degree bend. Any minor errors in position are absorbed by the flexible Tygon tubing.
AN4 tubing can make tighter turns, so maybe that would have been better for these connections, but I wanted the ram-air vent tube diameter to be as large as possible. Certainly the sight gauge connections could have been AN4, since fluid flow was not a critical factor with those. But then I would have needed AN4 to AN6 connectors, which might have elongated the system.
This area is never pretty in most photos of other planes I've seen. At least I have robust AN connections in most places instead of tygon tubing and nipple fittings everywhere.
Will obviously have to monitor all these connections for leaks.
