the fuel rail has 4 nuts holding it down, ( 4 outside corners) remove the injector clips, the vac line off the fpr on the rail, lift the rail up, the injectors will pull out of the lim, no real need to undo the fuel line. unless you want it off, then you'll need a 2 different size fuel line disconnect tools.
to change the O rings i found it easier to cut the old one off with a razor. oil the new one, roll it on. get some q tips, a lot of them, then clean out the injector holes real good, i used brake cleaner sprayed into the cap, dipped the q tips in the cap, then cleaned the holes. re oil all of the o rings, and slide them back in. bolt it back down, install the injector plugs and vac line..
if your changing the top o rings as well, theres a clip you pull out, then pull the inject or out of the rail. its easy to see how that part comes off. same deal cut them off roll a oiled new one on, put it back in the rail, re clip it.
