Re: bought a motor need info 5.5hp evinrude
As others have said, your motor has no fuel pump. It makes use of a "pressure tank" to feed the fuel system. One of the nipples on the hose connector, is plumbed to a nipple under the carb, on the intake manifold. This supplies pressure impulses from the back side of the pistons as the engine runs. This is why the correct tank for the motor has two hoses - one to supply pressure to the tank and one to feed fuel back to the carburetor.
There is a way to convert the motor to a fuel pump, but you have to take a check valve out of it. The valve is what keeps the pistons from supplying pressure/suction pulses, as the pistons move back and forth. In the pressure tank setup, you want pressure only, while you want both pressure and suction, in a pulse type fuel pump arrangement. If the conversion is done, most people use a Mikuni fuel pump, rather than an OMC part.
The easiest way to deal with lack of a pressure tank, however, is to surf EBay for one. They sometimes get a little pricey, but if you are patient, you can usually find one for a reasonable bid.
That's a great little motor and if you have something to put it on, I would keep it!
