unscrew the lines, i remove the hold-downs closest to the injector so u can get the lines out of the way. remove the return line that connects the injectors together. remove the injector hold down nut. screw a lug nut (yes a lug nut off ur truck) onto the injector, grab the lugnut with a pair of vice grips and pull it out. if its bein stubborn then take a piece of 1in pvc pipe and cut it to where when u slide it over the injector that a few threads show then screw the lug nut down to pull it out.

or you can weld a nut onto the back of that lug nut and use a slide hammer, i use a 4" or so bolt for the back two and a 8 or 10" one for the rest

the injector threads are 14mm x 1.50
therefore you need to go BUY a lugnut for a ricer...
our lugnuts a standard thread 9/18-18 i believe,
trust me, i used one off my truck and almost ruined the threads on the injectors ouch
