    dual fuel pumps 94 sl 750's

    Hey guys. Wondering if any one could answer a question for me. I have 2 94 sl 750's and I am in the process of converting one of them over to the 3 output fuel pump. I was wondering if the single output fuel pump could be used on the other ski. The skiis had been worked on in the 90's from a dealer who put T's in between the pto carb and the center, and between the center and the mag carbs which in turn gives me 2 fuel inputs. The main thing I was wondering is could I put a T on my pulse line and run both single fuel pumps to my dual fuel inputs. Really wanting to know if the pulse line would handle both fuel pumps. Thanks alot

    NO. Not a good idea to "T" a pulse fitting.

    Just break down and buy another triple outlet fuel pump for $26.

    Thanks for the reply xlint. I have seen other pumps on polaris, and wondering how they did it. Do you know?? I would think if I could run both my singles I would have alot more volume than buying another tripple, but buying another tripple is what I will probably do later.

    Some engines (primarily the domestic three cylinders) have a second pulse port on the MAG cylinder crank case.

    Mine are the blue fuji engines. I'll check and see if I have a pulse port on the mag cylinder. Thanks

    They have a second pulse fitting built into the case. OR, I've even installed a fitting into my reed spacer.

    If you buy a pentagon (stock 780 fuel pump) it's a High Output. Delivers nearly twice as much fuel as a normal (round) Milkuni triple outlet fuel pump.

    Although, a stock, or even mildly built 750 would only need a round pump.

    You don't.

    Only the PRO 785 engine would have it on a Fuji.

    Thanks alot folks, I will probably be getting another tripple output for this one, I was just wanting my other ski were I could build the heck out of it when I get ready to. I am going to be checking on Ebay for a 3 output pentagon pump, I believe they deliver about 65 lph, I guess that would be sufficient for anything possible.
