Thread: Could THIS Be Causing All of the Engine Fires?

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?

Wow congrats on getting that done so fast! When I lined up the old rings and the new rings before I put them in, I could tell the yellow ring shrunk a bit, so that, along with either a hardened/cracked or shrunk brown ring, causes leaks. At least youre leaks are gone. Good job.

My car had 118,100 miles on it when I changed mine.

No problem. I couldnt imagine what they look like. I think it helps if the rails have never been off the lines. I know when I got my car the UIM had been replaced, so I know my rings were disturbed. Id still change them for good measure.
