“The Motor I’m trying to specifically find the right tank for is a 1955 Johnson five and a half horsepower cd-12. I think it takes a pressurized gas tank.”
Yes it does simply by looking at the side connector which has a fuel and air connection
“I’m attached pictures of two tanks I have one dual line pressurized in one which I thought was dual line but I guess it’s non-pressurized” . ……………. A dual line tank is a PRESSURIZED tank
“The non-pressurized tank would go to what kind of motors such as years of make and type of model?.”
…. NON PRESSURIZED single line (hose) tanks work on all NON _PRESSURIZED applications generaly post 1959 or some late 50’S models as listed above in post #252644
“Also have a 1953 Johnson Q D14 10 horsepower , but it looks like it’s been retrofitted with an external fuel pump already.” ….. ODD these mods simply invole the mounting of a modern pump UNDER the cowl.
“Would the non-pressurized tank work on that?” if the QD is modified for a common modern pump then the tank (single hose) will work
here is how it is done… see utube. the mod requires the installation of a single line side connector … but the older 2 line connector could be use if you use just the fuel half of the hose of it leaving the AIR side in place and plugged at he tank end ….. just for looks on a vintage motor.
