I plan on installing a low pressure electric pump on my YANMAR 4JH engine. What is the best way to power it? To the "ignition/starter" switch, or a separate switch? It is a "free flow" so it can be left OFF and fuel will pass through it. I don't plan to use it all of the time, just to bleed the system. How have others done it?

Good advice – been there – done that. Ended up having to crack each of the injectors to bleed the darn thing. Why isn’t the Yanmar self-bleeding like other engines. To think of it, why does it not have an integral pump to aid changing the oil too.

One word of caution (first hand experience talking here) after you play with the fuel system make sure you have all the air out of it. The dang thing may crap out at the most inopportune time with just a wee bit of air. Run it in gear under load for a bit and listen to it. It is fairly obvious if it is happy. David F.

If this is really short, the pump is probably on the lobe of the cam. Turn the engine over a bit to get on the flat part. Hope that makes sense.

Unscrew the cup. Pull out the filter. Insert a new one. Fill the cup with new fuel. Screw the cup back on. Open the vent. Pump the priming/lift pump lever until the filter cup is fully vented. In case you don't know, the lift pump is on the right side of the engine, about halfway down and one third of the way forward of the flywheel. It will be the first thing on the engine that the fuel flows into. The filter is next in line moving forward. The lift pump should have a little flipper that you can push up and down to manually prime the system.
