Yeah... I had a giant plastic one in here. Switched to this smaller one. It's not recovery so just catch... I think it'll be sufficient... need to put a pitcock fitting on the top but think feeding from the bottom would work.
Think I need one for my Scamp I'm running a Griffin single core radiator and so far haven't had to add coolant but if I decide to take it to a 1/4 mile track they won't let me on the track without a catch can.
