Default Fuel drain and vent fairing PIREPs

Anyone have experience with these on flying RVs? I've purchased a set already but curious about use. They look nice IMO but do they make it harder to drain fuel? Add 5 knots They fall off at FL15 and hit people in the head, etc. Let me know what your experience has been with them.

Default Cool

They look cool - I use them. Doesn't affect fuel drain or airspeed

I have 4 of the blue ones for the fuel vents and for the vents for my Earthx battery fire containment box, plus the two for the sumps.

Per the "fall off and hit someone" question - the blue ones wont fall off. They screw onto the usual blue tubing firewall pass through connector. As long as everything is tight, they will stick around.

The silver ones for the sumps are different - they clamp on with a set screw. So, yeah, enough vibration and they could maybe possibly come off. But some loctite likely fixes that.

Default Work fine

I have them on my -10 for main and aux tank vents. I have a set of sumps but ended up using the flush sump drains; kept having leaks with the standard CAV-110s.

I used them just to skip having to glue a piece of stainless mesh into a cutoff fitting. Seemed like a more elegant solution to supply positive pressure to the vent line while flying. No issues with the silver ones falling off yet either.

I have them, the fuel drains lock on tight with the collet/set screw setup. The only gripe is that you can’t pull down on a leaking fuel drain like you can with the exposed style.
