I changed both yellow and brown in both lines for good measure. Although the yellow rings were not in as bad of shape as the brown ones, they were very soft and in need of changing.

when you replace injector o-rings do you usually replace both the ones on the bottom of the injector and the top, or just the bottom? If you want to pull the injectors out of the fuel rails, do they just pull out? and you just slip them back in with the new o-rings?

When you pop off the fuel rail, there is a metal slip retainer at the top of the injector that holds the injector in the rail. Slide that sleeve out and then the injector can be pulled out of the rail.

It is recommended to change top and bottom o-rings. As for buying injector o-rings, just ask at the parts counter. There are 12 in a pack I believe. Enough to do top and bottom.

Because if you don't replace all your injectors you risk getting a nasty vacuum leak or worse.

my bottom ones looked fine last time i looked. i don't know about the tops.

The bottoms go bad first. So if the bottoms are good, then the tops should be fine.

i went to store and got the o-ring assortment. only bought one since i already had the same assortment at home. Autozone didnt have the 12 pack o ring assortment for the fuel injectors.

honestly, i didnt think i was going to get the black retainer out. I fiddled with it for 10 minutes until i finally just took a tiny flat head screwdriver and stuck it in through the side opening in the quick disconnect, lodged it on top of the retainer and pushed down really hard. POP. came out lol rest was easy. Did the same on the rear line, except, you cant fish the flathead through the side of the quick disconnect. You have to go in from the very bottom and just pry downward on the top of the retainer even thought it is an awkward angle, and you feel like its not gonna come out. thise one was easier than the front for some reason...

pulled all the o-rings out, and to my surprise, they were not cracked at all. they looked good actually. On the rear, i dont know if i bumped the yellow oring while messing with the retainer, but it looked like it had been out of place or something. I was trying to make sense of my rear leak. idk...I put in all new orings and nothing leaks at all! i pushed and pulled an no leaking! so, o-rings looked good, but the new ones fixed the leak issue....maybe the old o-rings were too flimsy?

edit* my car has 97k miles on it, so i don't know if the engine fires are from these fuel line o-rings. Maybe just on the higher mileage engines?? SuperSport, how many miles were on your car when you changed the o-rings?
