Dual Tanks ? 84 Silverado

[X Baldwin Motion]

greetings, I recently acquired an 84 Silverado long bed with the dual tanks, what are the capacities of these tanks?

The rocker switch to change from left to right tank makes a clicking sound from right to left but not the other way. The gauge also goes berserk on the right tank. I am not really sure if the switch is functioning properly. Is there a schematic available that shows me gas tanks, plumbing and switching ? Is this switch prone to problems ?


Thanks in advance for the help.
