  • Fuel tank work__Mako 224 several questions

    Just bought a 1985 Mako 224 and love the boat, but it has been, lets say, not had stuff taken care of for awhile. I need to run new fuel hose,and vent hose, these are cracked pretty bad, they seem to be the originals. First question, do I need to remove the coffin cover,and if I do how much work is involved. Is it sealed or just screwed down, or can I just use the inspection plate to change hoses. 2nd. Que, what size is the I.D. sizes of the hoses so I can buy them before I pull the others out, I would like to use the hoses as a "something" to pull the new ones through with. Also I would like to do some kind of fuel gauge before covering up the tank. It has an electric fuel gauge there now, but it doesn't work. Does anyone know of a good unit to replace the other one with. I think I will need to replace both ends, sender and gauge. I really don't want to go with one of the expensive "fuel flow devices" Any help, experiences, or advice is wanted Thanks Don

      On my 21 there is no way you could change the hoses without pulling the entire coffin hatch. the inspection area is just to small. Those hoses are only about 18 inches long on mine. The rest of the run is made out of aluminum piping. That aluminum piping needs to be inspected real close. you may not need to completly remove your console but tip it up on its right side. and suspend it. This way you dont have to remove your steering assy. You still will have a few wires to deal with. The hatch is sealed down and will have to be cut with a knive best you can. /Then pried up carefully. The Id on my fuel fill hose was 1.5 inches. the vent Id was 5/8. Your Gauge assy was probably made by rochester gauges. and sold to the tank manufacture(florida marine tanks) My sugestion for gauge parts is to get them from bypass the middleman and his markup. you probably have a m6200 series gauge. you will know when you look at the site. The other alternative on the fuel deal is a complete fuel gauge package from one of the retail stores or mail order.. Hope this helps. dave. BTW I bet you a cold soda a naveman fuel management system for 140 bucks would pay for itself in short order with todays fuel prices. You will have 50 or so in a new elect. gauge setup. dave.
