    I'm fixing up my old honda 2500 genarator and I found out my gas tank is shot. The best price I found on another one is $180.00 and I don't want to spend that much. I was thinking of using an outboard motor gas tank. I think it will work. What do you think?

    i think you should buy the correct one that bolts on correctly. If you have a fire caused by the tank failure your insurance company may not pay. Maybe find a used one somewhere?

    What's the model number on this gen-set ?

    I don't see a top feed boat tank supplying fuel to a gravity feed carb unless it has a fuel pump.....

    Why not? Doesn't he just have to put it on top of the generator? What am I missing?

    the fuel outlet on a boat tank is on the top ,while a gravity feed tank has it on the bottom .Its harder to use gravity to suck fuel upwards out of the tank .

    theres a store up here in Canada [princess auto ] that sells surplus stuff ,tools,and other assorted crap [same tools as Harbour freight ,different colour though ] .Anyway ,I have seen genuine Honda generator tanks there for under $40.00 .These look like the tank a google search of your generator shows ,and even if its not exact ,I am confident it could be easily made to work for you .They have mail order ,and are usually very helpfull .

    Right, but isn't that why you have a primer bulb in the fuel line of an outboard? Either the engine's fuel pump pulls the fuel, or you use the primer bulb to pump the air out until the carb float stops you. Once the line is primed, you can siphon with gravity all you want. All that matters is that the end of the line is lower than where it starts in the tank, not the path the line takes in the middle.
