Well I had my first problem about a year ago. The little hand pump that's built into the Yanmar engine is pretty terrible too. I went to the marine store, bought one of those squeezy-bulbs the outboarders use, and spliced it in the line downstream of the fuel filter, but before the engine. Five or six good squeezes and I could hear fuel dropping back into the tank from the return lines, and the air was bled out. Piece of cake.

Re: Bleeding your Yanmar Engine

I believe your picture showing "fuel injector pump" is wrong.
That is the fuel filter assembly. It is not high pressure. High pressure starts @ the internal fuel injector pump.

The bleed valve attached to the high pressure pump is on the low pressure side.

Re: Bleeding your Yanmar Engine

Sellongitab is correct in pointing out that the article and photos incorrectly identify low pressure bleed points as high pressure ones.

The fuel is pressurised by the high pressure pump after which the fuel lines are all metal pipes not rubber hose and there are no bleed nipples. If you need to bleed the high pressure side you need to crack open each injector feed pipe.

If this could be edited a good article would become even better and less likely to cause confusion to newcomers.
