case 444 and 646
I have a case 444 and lost fuel pressure. I replaced the pump but can't get it to prime and pump. Is there a trick to priming a gas fuel pump on a Kolher 14 hp engine in a old case 444?

No trick to it. Is the pumps lever riding on the cam properly?
Can you get fuel through the line to the pump? Some gas tanks have a screen filter inside the tank, sometimes attached to the petcock.

If you pour a little gasoline directly into the carburetor, the engine should start and the pump will kick in.

The K321 engine has a mechanical pump that shouldn't need priming. I've rebuilt a couple of these motors including replacing pumps and have never had to prime one.

I'd check fuel lines for a good flow and also for dry rot/cracks.

Here's a site with tons of info on the Kohler engine, the page linked has info on your fuel pump Information about the Kohler Carburetor, Various Fuels and Fuel Systems

I recently replaced the fuel lines and there is no petcock. when I dip the fuel line lower than the tank no fuel comes out so tomorrow I will disassemble everything and check for a pinch or blockage. Thank you
