Fuel Venting from left reserve tank

[GMPoland]

After an extensive look at the fuel system in my aircraft the problem was found. seems that during previous maintenace the plackard on the overhead fuel panel had been installed reversed. Thats right. BACKWARDS. This was an easy fix, However, realizing the potential for disaster during the previous flights over the past 15 months has made me very cautious about checking up after the mechanics have worked on my aircraft. And for all the replies, Thank You for your advice. the information was very helpfull.
