Fuel Injection Pump

[sherpa]

I have been told my injector pump may need to be rebuilt on my Kubota B20 TLB. I was told I need to send it to a fuel shop somewhere in Charlotte, NC. Does anyone know anything about what I am talking about? Is the injector pump hard to remove from the engine, is it something I could do? Is it expensive to get a fuel injector pump rebuilt? I called the local kubota dealer and he said he did not repair fuel injector pumps and he would have to send it off for repairs.
I use the tractor every day, its just a little under powered and is hard to start. I had a tractor person look at it and he said it needed the fuel injector pump rebuilt. He based this on the hard starting and slow acceleration.

Is it possible to do an output pressure test on the injector pump. This should tell the tale.

Rebuilding is most likely best left to shops with all the proper equipment.
