Does an outboard 6 gallon gas tank have a filter sock on the pickup tube?

Yes, I have a 6 gallon fuel tank for my Johnson Outboard and after it stop keeping the primer (black bubble) hard due to air going in, I took it apart. Found the problem was a broken plastic line that was taking air.... At the end of this plastic line (seating at the bottom of the tank so it can empty the whole tank) there is a mesh type filter, so the fuel that you put in is pre-filter before going to the outboard main filter.... Hope this helps,
