Fuel injector O-rings, please help

[Punkin]

One problem down, now another...any insight on replacing the O-rings on the fuel injectors..I have a 90 240sx a couple of the old ones were dry rotted and leaking. We got the o-rings specified for the car and have replaced them several times...still leaking. How do you get them all on and lined up to stop this leaking? Thanks for any input.

You can't use the metal cap to push the injector all the way in. You have to push it in by hand. If you use the cap and screw it in it will tear. Other than that.....I don't know.

u could also check if its the injectors them selves leaking, i had that problem in my 90'240 and i bought the whole kit of injector seals and o rings but it ended up being the injectors that were cracked....i just went to my local auto recycler and pocketed four new ones, now it runs prime :D :D :D
