Fun Deck Gas Tanks

Repeating a question from another owner as this is very applicable:  "noticed a lot of water/trash in the fuel tank.  Is there an easy way to drain and flush out the fuel tank?  Also, is there any schematic of the fuel system including wiring,fuel lines, fuel pump?"

I have the owners manual, but it does not provide any useful detail.

    Any luck?

    I need to do the same thing on my 1991 FD196.  Seems only easy access is through the fill tube?   Was thinking I would wire up an old fuel pump to the trolling motor battery and suck the tank dry through the fill tube.  Obviously need to be mindful of keeping the electrical connections away from the fumes.  

    I also considered removing the sending unit (since it doesn't work anyway) and run a hose down to the corner.  From what I can tell the tank lives beneath the bench seating on my boat, but be danged if I can figure out how to access it.

    Unfortunately, there is no easy way as the fuel tank and their systems are installed before the top deck is mated to the hull.  Using a siphon or suction pump accessing through the fuel fill is pretty much your only choice, unless you have a an I/O model.  I can access my fuel tank and sending unit by removing my back seat engine cover.  If you need a new sending unit and don't have access to it (just make sure you opened all the existing deck plates first), then you may have to cut a hole in the deck and install a deck plate to fill the hole and provide future access.  A Hurricane dealer should know where to do this (or have them do it).

    The fuel pump and filter/water separator is usually associated with the engine manufacturer, not the boat.

    I can get you wiring diagrams for your boat, just send me a Personal Message with the e-mail you would like me to send it to.
