I will post some pics I apears to have a pump I think it’s a puls pump I have a similar one on my sled. Install looks legit I wouldn’t have known it wasn’t stock but yea single line to tank. My boats rated up to 100hp I’d love to put more then one on it. I will put more oil in my mix I found the 50:1 odd but read it on another form wanted to check in with people who knew b4 I tryed it though it might make less smoke lol. Won’t have time to tinker on it till early next week will let you all know how it goes.
