Can you upgrade the injectors on a B1750?

I have a Kubota B1750. I have an injector that is leaking. I was wondering if there are larger injectors available or any type of upgrade. Maybe get a little more power out of this thing.
Thanks
Mike

Fuel delivery is controlled by the injection pump not by the injectors.

Thank you. Could I turn the pressure up or is there no adjusting these? Sorry for the stupid questions, I am new to the tractor side. Been a hotrodder my whole life though.. so I always see some room for more power..lol

Why certainly. If you got the money,there's shops specializing in diesel engine hot rodding. As millions of pickup truck owners learned the hard way, there's more to it than bigger injectors,jacked up pump or propane injection unless you only need it to run like a bat out of hell for a short period before throwing a wiggle pin or bending the wobble shaft.

It is not pressure but volume you must increase. There is an adjustment that limits the travel of the rack. By changing this it increases or decreases the max fuel that can be delivered. A little goes a long way.

Just remember you are dealing with an engine rated at 20hp. You are likely not going to get 30hp out of it. 10% is probably a realistic expectation.
