Here is my standard blurb....
Injectors are easy, remove the line cap nuts, gently move the line away sufficient to remove the return lines/caps as a set per side, then using a 1" socket "DO NOT BEND STEEL LINES" unscrew the injector(s). Remove the copper seal if left in the base of the bore.
If major amounts of carbon are found or difficulty in removal of inj or gp place the cylinder at TDC. Clean the inj bore but do not dump carbon into the cylinders, remove the GPs and use a vacuum to clean/suck debris out through either hole.
Send injectors out for pressure testing at a local shop or just buy new ones, also get a return line kit which consists of hose, clamps, orings, copper seals and new injector caps from one of several advertisers here.
Installation is reverse, "DO NOT DAMAGE THE NOZZLE TIPS" you can put the "new kit orings" on the injectors but they come with some on already. To replace useing vaseline or??, roll the first oring into first groove, roll second over it to lower groove trying not to cut them. Put the new copper seal on injector tip, I hold it in place with antisieze, antisieze the body slightly and do the threads, torque to 35lbs, book says twice?. Install the new caps and line "sets" made up "by you" identical to removed sets, use more vaseline inside caps, press down on cap (tops) until they seat into place. Connect the line caps torque is 22 ftlbs.
Now would of course be a good time to replace the IP too as your 75% there.
If you do not replace the IP starting should be no problem as fuel is at the end of the lines already and several cranks will fill injectors.
If you will replace IP, I would replace the fuel filter a few days prior. The driving would allow the system to have removed all air from that change before introducing more with the pump change and line removal.
