I'm blessed to fly both an RV-14A and an -8.
When I top off the tanks on the -14A, if the day significantly heats up expanding fuel will drip out the fuel vent tube(s) onto the tarmac. This seems normal.
On the -8, though, I sometimes see blue Avgas streaks emanating from the closed fuel cap and going down the top of the wing. Shouldn't thermally expanding fuel follow the path of least resistance, i.e. thru the vents?
The engine (IO-360-M1B) has always run fine, but I'm concerned about possible fuel vent blockage. How could I test for this? Any thoughts appreciated.
