9. important to understand how the bottle valve and siphon tube are assembled to properly orient the bottle in your vehicle and ensure that it picks up liquid nitrous while undergoing acceleration All nitrous bottles are assembled so that the bottom of the siphon tube is at the bottom of the bottle opposite the bottle label An Edelbrock nitrous bottle cannot be mounted upside down Edelbrock does not offer a non siphon tube bottle for automotive use If the bottle must be mounted parallel to the axles of the vehicle sideways the label must be angled at approximately 45 degrees toward the front of the vehicle This orientation will position the siphon tube toward the rear and pointing to the lower rear facing quadrant of the bottle All of this positioning information is critical to system operation It is most important to draw as much liquid nitrous as possible The siphon tube cannot do this unless the bottle is positioned correctly ia The most efficient mounting is the lay down position with the valve handle toward the front of the vehicle This position allows the greatest amount of liquid to be used before the siphon tube begins to pick up gaseous nitrous oxide Catalog Part 70402 Page 9 of 25 2003 Edelbrock Corporation Brochure No 63 0164 Rev 02 03 2 3 Nitrous Bottle Installation After you have determined the location and orientation of the nitrous bottle use the following procedure to install the bottle 2 3 1 Stree
