1994 204 DCX Champion Questions

I have two questions about this boat that I purchased a few years ago.

1. I am having to disconnect the oil injection system and need to know the size of the two gas tanks on board. The mainand aux

2. There is a fuel selector switch located in the rear drain well right in front of the motor. I am unable to tell in which position should the pointer point to select either the aux or main tank. I guess the notations have worn off to the location of the two.

Thanks in advance for any help.

no idea about the size but whatever side your arrow is pointed at is the one it pulls from.call b&j marine they may be able to tell you what size they are.
