Fuel pump on the engine has manual level, to pump fuel up manually. It is hard to get to on Yanmar 2QM15. Fuel pump located under fuel filter, the filter’s input fuel line starts at fuel pump, it is small round shaped thingy. There is a level under the pump. You need to pump it, make sure you bring it all way up on every stroke.

1. Fuel filter(screw on top). There is disposable plastic washer under it, you need to replace it frequently
2. Fuel return lines on injectors, start with rear one. There are cooper crushing washers, need to be replaced when crashed
