ahhhhhh, the leaky fuel injector. had the same problem myself. ok, this is just off the top of my head, but, i'll check my helm's manual to make sure when i get home. but, i believe you need to rings, the o-ring on top of the injector and the rubber ring on the manifold. there are three rings but, i was told not to replace the very bottom ring on the manifold because it rarely needs to be replaced. buy those at the dealer.

ok, this is simple and straightforward procedure. this is from my experience with a ls integra, you remove the bolts that bolts the fuel rail down after unhooking the fuel lines from the factory fuel pressure regulator but it isn't necessary to unhook the fuel line from the fuel filter. after doing all that, unclip the harnesses that leads to each injector. you do this by using a small screwdriver and prying off the metal clips to the side. unhook those and pull the entire rail off with all the injectors intact. pull each one off and replace the o-rings from the fuel rail and the rings on the manifold. but before putting the injector back on the rail with the new rings, oil them up with motor oil so they'll slide back in.

install them with the reverse procedure.

like i said, i'll check to make sure if i've missed anything from the helm's manual. so, anyone correct me if i'm wrong. this is based on a vague memory of the procedure.

 

that sounds pretty complete to me.

 

you do not need the ones in the manifold. Greddy uses RC injectors on the RC injectors the rubber rings that go into the manifold are differnet then stock. Out of the 10 times i have had my injectors out i have never replaced these and they never leaked. The real problem is the o-rings on the top of the injector and you CAN use stockers on the RC injector.

and you do not have to unhook the fuel lines form the rail. There should be enough slack in them to get the job done. I did not do this when i changed injectors last week.

you need to unbolt and remove the rail
make sure the injectors and the o-rings go into the rail smoothly.
Becareful of tearing the new o-rings.

 

Yes you need to unbolt the rail from the manifold. you do not need to unbolt the fuel lines from the rail

 

there is only three bolts into the manifold and two the hold the wiring harness to the Fuel rail. I did not remove the return line on mine. But the return line is on the right if you are standing infront of the car. (driver side) The return line is attached to the FPR.

use a silcon spray on the o-rings so you do not tear them. Do not force them they should just slide in.

yeah, with the rc injectors they come complete with the necessary rings and you don't use the very bottom rubber ring with the rc's because the injectors and rail sits too high and you can't bolt the rail back on the stud. i'm assuming that he is just changing the rings on the factory injectors. it is more than likely that it won't leak if you don't replace it but, better safe than sorry. it beats doing the job twice and all the rings, top o-ring and bottom rubber rings will run you about $18 total at the dealer i believe.

oh yeah, also very important, relieve the fuel pressure by opening the gas cap and taking the fuel line off the banjo bolt on the fuel filter first before doing anything with the fuel system.

vaseline? that is for your own pleasure and not to be used on your vehicle. j/k. use oil

Once you remove the bolts holding the fuel rail on, you should be able to lift the rail off the intake manifold. The fuel lines are long enough that you can lift the rail up without detaching them. More than likely, the injectors will come out attached to the fuel rail; they just pull straight out with very little effort. I'm not sure if there is any reason not to use vaseline; I have heard it may damage o-rings, you'd be smarter to use some motor oil. If you don't have any motor oil on hand, you really should make a habit of carrying some around with you!
