On mine, IIRC, once the white knob is unscrewed it moved in and out like a bicycle pump. But yours may not be that way or my memory chips are corrupted.
If in doubt, just crack the injectors and spin the engine.
Oh!! Duh!! I’ll give that a try. I unscrewed the one like that on the aqua hot but couldn’t figure out how to work it.. I’ll try this on the generator. Fingers crossed.

Not at the moment. I keep it in a building about 15 minutes away.. I believe it’s the 20kw Koehler with the yanmar engine.. I’m like 85% sure anyway
On my Yanmar there is a lift pump. My finger is on the plunger. The other pic shows wrench on the injector fitting. Loosen all 4 injector fittings. Pressing that lever repeatedly will prime your fuel filter and fill the lines up to the injector. Once bubbles are not coming from injector tighten the fitting.

Dennis, if your set is a Kohler, it won’t have a manual lift pump. Kohler uses an electric pump. Without pictures, you could have a solenoid that is directly connected to the injection pump or, it could be mounted to the block with a linkage. Either way nothing happens until the injection pump rack is moved to full fuel position, then the governor takes control..
If you have introduced air, it will need to be bled first.
Give me a call, if you like, and I’ll be glad to walk you through your trouble. 614-271-7488, leave a message if I don’t answer please.

Mine looks identical to this one that Mitchel Stapleton has.
