				How many of you have drilled a 1/8' hole at the back of the fuel vent tubes [just above the angle cutout] to stop siphoning ????? Is it really needed ???  Cheers T87

 I don't see what you are referencing in the SAMPLE book you posted.  To the best of my knowledge the vent gets cut on a 45 degree angle which faces forward.  This is done to create a positive pressure inside the tank during flight. 
 
 Could you point it out for me? Or give me a search term to find what you are referring to?
