Hi on the fuel injectors there are O-rings and these little c-clips, it seems that the local car parts dont have them at all, and the dealer dont carry them. So I bought these smaller o-rings that are about the same size, uhm 7mm 11mm 2mm, yeah slightly smaller but it fits on the injectors, now this wont cause a problem will it? They wont like break under heat or something? Or must I painstakingly search for the exact same pieces the dealers dont carry anymore?

Ack no don't do that.

I tried to use some O-rings on my jeep injectors that I thought were about the right size and they still leaked all over.

Your best bet is to do one of three things:

1. Go find a 4Help catalog. Any local Advance or TrakAuto should have one. 4Help stocks all the little parts that get broken or lost on cars. They might have the O-rings and clips.

2. Contact one of the companies that offers sonic fuel injection cleaning services. You can find lots of them online and the prices vary from between 10 dollars an injector to 25. All of them use essential the same cleaning procedure so just find the cheapest place. They will be able to replace the O-rings and might even have new clips too. If you don't want the injectors cleaned or have already cleaned them then just try and find out if they will sell you the parts you need.


Here are two different companies that do the service. Cruzin Performance I have talked to before and they seem like great people and have a good rate of only 11 dollars per injector. RC Engineering have a great engineering/racing rep but also cost a lot more money.

If none of those other ideas work then go to your nereast junkyard and see if any of them have the parts you need on a used vehicle.

The o-rings on the F/Injectors are reuseable. Just have to lubricate them before putting them back in. As for the clips, they're not real important as the connector WILL stay on w/o them (mine has now for awhile now).
