Fuel O-rings (Page 1/1) Brent7088 JUN 23, 04:06 PM I've been ordering o-rings for the injectors and lines and had a little difficulty finding out where 2 of them go. Can anyone tell me where these are installed? Thank you Spadesluck JUN 24, 06:26 AM They could be the return and feed o-rings on the motor itself. Its hard to tell but it should be pretty straightforward once you start digging into things. fierofool JUN 24, 11:31 AM Those look very similar to the O-Rings that go on the fuel lines where they connect to the fuel rail. I didn't buy the Standard brand, but the ones I got did look just like those. shemdogg JUN 24, 02:58 PM I dunno but they could be the oring for the cold start injector. The fuel lines have o rings at the fittings too, looks like the brown one shem Brent7088 JUN 24, 06:21 PM Yes I finally found out they do go on the 2 rail lines... thank you.
