Oh! Got it. Your right, the first restriction is the very first inlet. Now with me maintains the stock stepped on and reserve tubes it won't flow more. But it you were to do that it would, and you would only have on and off. Might as well buy a pingle. But I would feel a little more comfortable with separate lines. One hose to the T and then into 2. Split. Now obviously it just fills the bowls and maintains a level setting. On wide open runs your splitting it. Can a stocker drink more then that? More then likely not. But I'm not trying to reinvent the wheel. I'm just trying something to see my results, it looks pretty cool IMO and its a cheap easy mod that YOU can physically do in your garage.
