I have 4 X1 dosing pumps and they work really good. The only thing I dont like about them is the tubing they come with. It's smaller then standard line so it doesnt fit on barbed fittings or push connect fittings. So I had an old jebao dosing pump sitting around. The head fittings on the jebao go from really small to standard size. I took two of them off and tried them on the x1 and they fit the end was just small enough to get the fitting on the x1 head. So now I can use standard line on the x1. I figured I would post it up .jebao fitting and tubing
