Nice 1.5 quart tank. It appeared as though it would come with the outlet fitting, it did not.

I bought two for my Rotax 582. One for the oil injection system and one for the coolant overflow. The gasket in the cap that I used for the oil swelled up almost immediately and stopped sealing. Any time the tank was more than half full the cap would leak oil with any amount of sloshing or vibration from the engine. The same thing is starting to happen with the tank Im using for coolant. (about 6 months of use so far) The tanks and caps themselves are fantastic, but it needs a different / better gasket material.
