Re: 1999 Yamaha 150 2 stroke fuel filters
If the motor is carbureted, there is one filter mounted on the port side of the motor.<br /><br />If the motor is fuel injeccted, there is one on the port side of the motor, a screen on the high pressure pump inside the vst tank; on the fuel pressure regulator; and in each injector nozzle. (these screens can get plugged up - I just had to clean all of mine on a s250txrv) There may also be a fuel filter mounted on the boat.<br /><br />The model number is on the port side of the outboard near the bracket. It indicates the type of fuel system; the model year; the shaft length etc.
