Ok, so it has taken me what seems like forever to find an get these gas lines for the top vent tubes but now that I have them installed the left hand tank has the line fastened on, and the tank is fastened with only hand tight bolts. Because this is a '76 build date it features separate tank connected with (1.5 SAE) hose, that hose lists for $16.00/ft. That is in place as well...I need to have some work done to the in-tank suction devise before its installed and the right side tank lifted into place...
