How to rebuild a 7.3 injector new nozzels

To purchase http://www.codythecarguy.com/store/product/ford-7-3-nozzles/ I broke down a injector so you can see the working parts and how the new nozzle goes on it. Also o-rings replacement and how the solenoid goes on it. These injectors have a mini p&b in them also known as the plunger that moves the fuel through the metering valve http://www.codythecarguy.com/store/product/7-3-injector/ http://www.codythecarguy.com/store/product/ford-7-3-nozzles/
