I have a kubota m9000 it's leaking antifreeze from a rubber hose behind the injection pump. This line is metal part of the the way with rubber hose on the ends. Is there a way to replace it without removing the injection pump?

Sounds like the line to the oil cooler, but that's a guess.

Post a picture of the leaking pipe/hose.

That does look like an oIl filter cooler line.
It goes to the water pump housing.
And yes you'll have to remove the injection pump to get to all of it.
They hid a bolt (140) behind the pump.

OK that's what I was afraid of. I have all the nuts off the injection pump. I'm guessing I'm going to have to take the front cover off the engine and take it lose from the gear since it still seems to be held in doesn't slide out?

Just a few pictures and a follow up I had to take the hose off the water pump, remove the injection pump cover to get to the drive gear, and fuel bulb to get to the hose

I hope you marked all the Injection gears before removing it all as that's the timing.

Do you have the WSM (aka service manual) for it?
