    Looks good, I do have a couple questions. How long is your pulse line? and did you disable the internal fuel pumps in the carbs?

    Bill, The pulse line is abought 10" long, It is connected to the rear cyl. and yes I did disable the fuel pumps on the carbs. That is the fuel / air separator I was talking abought. This is mounted on the left side of the ski and is higher than the motor so no fuel will run back into the fuel pump pulse side.

    Looks super clean in there. How can the pulse line only be 5" long?

    Well.......Mabe 8" or 9" long. It just runs from the original 3rd cyl pulse fitting to the bottom of the external fuel pump on the left side wall of the engine compartment. Do you forsee a problem?



    Hey Pistonwash........Thanks for the compliment!

    I'm not sure, but I would think the longer the length the weaker the signal. I would use stiff hose or thick walled vacuum hose for this. Maybe not a concern at all but just has me thinking. Maybe somebody who runs externals will chime in. Most of the time I see them mounted on the carb side of the hull. By the way carbs are great looking you did a beautiful job in the motor compartment.

    Bill, Thank you very much. I thought abought the pump placement also, I believe it will be ok fine because the pluse line is thick walled stiff oil hose. Acutually it is Parker Pushlock high pressure hose I got from work.
