Im on my phone so these pics prolly gonna be big here is the push in fittings. and the bottom of the pet cock...it will probably be a few months before you have to drain it...if then..
10 An. you can see it at the bottom of the first picture. And I MEAN they only give you enough hose to make it reach just like I got it... I had NONE left over whew! I think I measured the short line first to fit then what was left , the long hose... or wait was it vice versa... any ways.. not an Inch left. lol. One Catch can was all that's needed.
