Fuel Injector O-Rings
Saturday, February 11, 2006 10:14 AM
I went to crappy tire today to buy fuel injector o-rings and they only had 1 pack for one injector plus they want like $7 for three little o-ring. I can't wait till monday for the other ones to come in either so I bought a o-ring assortment pack, but it doesn't say I can or cannot use themfor fuel applications. Should I wait and get the proper ones? or will these do?

Ok So I found a parts store that had all 4, I got them got the old injectors out and now I'm lost the old injectors only have two rings on them that I can see, the kit has three in it(1 small, 2 big) am I missing something? Plus I broke some of the plastic retaining part of the one injector, how bad is this? It looks like it would still stay in place.

The car is a 96 2.2 Cavalier

Please anyone? How many rings are supposed to be on the injectors? If only two anyone know why they give you three?

Don't know about the number, but injector o-rings need to withstand high pressure, heat, and exposure to fuel. Your average, typical rubber o-ring doesn't stand a chance. They will set you back a bit 'cause of the special material as well as being a specialized size for an application that doesn't usuall need new rings often, or at all.

you have a 95 i think. Those are bottom feed injectors. 2 Orings. one big blue one at the top and one black smaller one at the bottom.

You should consider replacing that screen that you broke as well. Make sure you have seated the injectors all the way back in othewise you will flood your engine and may actually push enough fuel in the cylinder to lock it up.
