2 cycle boat motor fuel system?

Question

I have never owed a boat, it would look to me as though it would require a fuel pump. I am wanting to add a boat tank to my generator. I think I will need to either place the tank above the motor or use a fuel pump. I have been told that I will not because of the boat tank. How can that be? Is it possible that the 2 cycle boat motors have a built in pressure system that is created in the crank case by the down pressure from the piston?

Answer 1

u need pump or tank above....

Answer 2

Your 2-stroke generator likely originally had a gravity feed tank (the tank needs to be higher than the engine to get fuel to the carb).

An outboard boat motor draws its own fuel; there is no fuel pump in the tank like there is in a car.

Inboard motors are a different story. Some have fuel pumps mounted next to the tank, some just have fuel pumps mounted on the engine.

Answer 3

the tank will have to be above the generator because it is gravity feed,  boat motor have a fuel pump to pump the fuel but there is a fuel bulb between the tank and the motor you pump the fuel to the motor and then the motor pump takes over.
