I just bought an 415-C with a Continental 85. During the trip north from Ft. Myers the fuel gauge on the header tank would occasionally show fuel bubbles in the glass tube in level flight but the problem would get worse during landing and takeoff when fuel leaked out of the gauge. On the last leg of the flight the top blew off the glass tube while in level flight. All three fuel gauges are brand new. Mike at Skyport suggested I check the vent holes for blockage but I found none. I'm stumped and could use some help.
