    Dual Fuel Pickup Installation

    Yes

    Here are two pics of Fernando's dual fuel pickup modification from his website.




    You disconnect the main supply and reserve supply lines going to the fuel knob.

    Run new fuel lines from the fuel sending unit on top of the tank to two new fuel filters.

    You will have to purchase a new fuel filter mount to add the additional filter and rivet the bracket to the hull deck next to the existing fuel filter.

    From the two fuel filters, run fuel line to the carbs as my diagram shows below.

    You will no longer have the fuel selector knob in the loop.



    If you plan to install a primer kit, you need to remove the fuel selector knob and install the primer in its location.

    Pull the primer supply from the reserve line with the t-fitting that comes with the primer kit.

    A rubber Vacuum cap.
    Can be found at any auto parts store.
    They come in the assorted pack or you can get the size you need.
    I beleive it is a 1/4" size.

    I have a question.. I think I am going to do this, since I am going to replace where the nob is at with my primer kit plunger..

    1: can you put up the diagram your talking about..? I don't know where to run the hoses from the filter to the carbs. Will I get like a Y fitting to connect the tubes to go into 1 fitting on the carbs? ( please post the diagram)

    2: how many ft. or fuel line should I buy? What kind of tubing.. size, should I get the tubing from riva or what?

    3: How do I get the fuel selector piece off of the hull? I can't get it off.. how did you get it off?

    4: what hose is it exactly that you cut into for the T-fitting that will go to the plunger? I thought there will be no reserve line? do you have a picture of the line...?

    5: Do I need to worry about that like pump thing you have in the background of the picture?

    Thanks..

    Hey Kale...

    First up its pretty unlikely you'll need to run dual fuel lines..
    As an example i didn't need/use them when i was running triple pipes..!!

    If you do want to go ahead anyway then:..

    The fuel lines used are the main line and the reserve line

    The main line will be extended to the bottom of the tank the same as the reserve line is..

    These two fuel lines go through separate filters(as seen in the pics you posted)
    From the the filters the fuel lines then go to the carbs.. they get tee'd in between #1 and #2 carb, then between #2 and #3 carb
    The original fuel inlet gets bocked of on #3 carb..

    The little pump thing you are asking about is likely on the return line on that ski in the pic..
    Probably used to prime the carbs..(you don't need it..!!!)

    For what you have and want to achieve:.

    If it were me I'd remove the fuel selector switch..
    Take out the little Phillips head screw in the middle of the red knob..
    Lift the knob clear.. under this is a decent sized nut.. unscrew it and the selector is free to come out the back..

    Next set it to reserve and leave it there...(zip tie it down to something)

    Now from there i'd tee into the main fuel line just after the filter (carb side before the switch) for the primmer kit..

    Next up install your primmer in the selector hole.. you'll likely need some decent sized washers..??(and some sealer)

    That's it your done...!!!

    Why do you think you need to go dual fuel anyway..??
