While working on replacing my rusty fuel lines yesterday on my '76 W200 it got me wondering more if my truck might have came with an auxillary tank in the cab. The fuel lines on my truck run to the outside of the frame on the passanger side between the tank and the fuel pump. From looking at diagrams in my manual I noticed that this is where the selector valve would have been located from the factory, although that valve is not present on my truck currently. This has me wondering about the line "10 Gallons Gas" on my Equiptment Identification Tag though. Does this options refer to an auxiliary gas tank in the cab, or is it just simply stating the truck came with 10 gallons of gas? If this truck did at one time have an auxiliary cab tank where would the tank selector switch have been located?
