Awesome, Thanks for the quick reply!

Thanks for the help! Put the new pump on and it's running great now!

I'm working on this L4400 and just put a new injector pump and fuel pump on it and got it running great now but when I was putting it together noticed a rubber hose running off the front axle to the top of the engine. I think it's the vent hose but want to make sure it wasn't hooked up to...

Lol. Just used mouth pressure. Definitely not compressed air. I’m gonna get a new pump and hope this does fix it. I’m sure it will.

Thanks, sorry for the simple questions. Just learning the diesel engine stuff. lol

Appreciate it! Now to get it rebuilt and back together.

Got the tractor this morning and the pump off. Actually wasn't as bad as I though. There's a place that rebuilds them within driving distance so I'm gonna take it to them for service but I have one more question. I noticed this tag on the block and have no idea what it means? Thanks again for...

I kinda figured that was gonna be the answer. Lol. Thanks for the quick replies!

While I'm a good auto mechanic, this is my first time working on this. I'm attempting to fix a friends 2010 Kubota L4400 (I think it's a v2403?) that I found the injector pump to be bad. Number 4 cylinder just dribbles fuel out of the line. He took it to a Kubota shop and they verified what I...
