I started this message after reading some responses in a builder's log. I have four fuel caps. All of them have the vent pointing in an angle to the relative wind. In some of the other message replies there were mentioned a twisting of these vents until they are in the right direction. My question is what is the right direction. I've been flying for 60 hours and have had absolutely no problems with fuel flow so I'm assuming the fuel vents are doing a satisfactory job but, I have also wondered why the vents were not made to point directly into the relative wind rather than at an angle. I wonder if they are at an angle so as not to over-pressurize the tanks. Anybody know what the scoop is on this?
