I made these today for my 6A. The holes are .035 dia. 19x. Question is, will these provide too much pressure in the fuel tank with the ram air? Also should I drill a small hole on the back side?
Just don't suck the air out of the tanks when facing them backwards. I don't know if that would be the case or not though. Thought I'd throw it in for a learning moment.
OK, I drilled a small hole in the elbow corner at about 45 degrees face downward... Installed these on my plane and they look pretty good. Maybe my angled weep hole will whistle and scare deer!
