73 duster vented gas tank ?

Do you actually have that 5 nipple monstrosity in your 73? Our 318 73 Gold Duster had the little rubber connector on the top to a 3/16 steel tube like 8 ft long looped to a spout under the upper rear shock area. We put a 3 line Omni filter in and used the steel line as a return to the sending unit extra nipple.
Mine just has the nipple at the top of the tank above the sending unit. There's a rubber hose that connects to a steel line. That goes all the way up to the passenger side on the interfender and Bends up to a Thirty five or forty five degree angle and that's it
