hi all my tractor has been getting air in the fuel filter housing and i found the primer pump had a small leak that would allow air to enter and give codes and quit running so i replaced the fuel filter housing and now it gives code f06 1613 that is for injector bank 2 fault does anybody know what that is, This tractor is driving me crazy. and it has also blown a 10 amp fuse for the engine sensor. and lost all power when that happens. i would appreciate any help thank you
