I have a kubota b1550 that I rebuilt a while back and you guys gave great advice. The tractor runs great but at some point the injector or injectors fail and allow compression in to the fuel system which put air in the system. with the injector line off you can feel the compression coming out of the injector where fuel should be going in... Any idea what causes this and what I can do to stop it? This is my 3rd set of injectors. I have dual fuel filters installed

Buy OEM or Oregon Fuel Injection injectors if you have been getting your injectors from the internet. If you have been having the failure with good quality injectors then I have no idea.

I would get a new set of OEM injectors or at least replace the failed injector(s) with OEM injectors. They are not TOO expensive at about $110 each from dealer.
Oregon may be cheaper?
Just be careful because there may be a part number change depending on tractor serial number.
I would recommend you replace the copper sealing washer underneath the injector also!
Good luck!
Yea I think I will order them tomorrow through Kubota as well as the copper seals... Thanks for your help...
