it's not 2 tanks - it is one split up....
You have 2 tanks if you can select them individually.
On any R you switch
the tank ON or OFF.
As a matter of fact: the aux-part of the tank drains into the main-part of the tank and then there is a line going from the main-part of the tank down to the gascolator.....
On the II models the return line from the fuel-pumps T's into the connecting line from the aux to main....
