fuel injectors

Should also have asked in my previous post if anyone knows the interchangeability of 'Branson' Fuel Injectors with TYM's or other mfg's (mine have p/n HK12020000A3 on the bag. Original injectors have '78-0090' & 'F 7 L' stamped on them; ones I just bought have '78-0090' & 'D 2 E' stamped on...

Greetings, all. Putting this in the TYM slot because of them now owning Branson and I believe they still use Kukje engines with mechanical injectors. Question: is there or is there not a "cup" at the "head" end of an injector (in my case a A1700; 2011 vintage engine) that can/should be pried...
