Alright, here are the instructions....they suck. http://the-sanders.com/images/Humor/Acerbis.jpg My question is the top right diagram I do not understand??? It goes along with the instruction, "Drill an 8mm hole in teh ACERBIS fuel tank and insert the fuel vent...." ???? Isn't the fuel tank already vented from the gas cap? See pics of the gas cap and the additional fuel vent they want me to drill into the tank? Secondly, they want me to screw the petcock directly into the plastic tank? What I can do to better ensure that the screw seals to the plastics without creating a possible leak?
