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

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.

Funny thing that I seen this thread. I was changing my Orifice Tube today and noticed a slight smell of gas. I just happened to move the fuel line when I unbolted and moved the brake booster. The odor got stronger. I stopped what I was doing and traced it to the rear quick disconnect. I was just thinking about how to fix the leak! Looks like that project will be tomorrow. Glad I caught this thread!

Bump for anyone who has not seen this thread.

From the original thread:

I was aware of the write up here on GPF that walks you through changing o-rings for a GTP, but was unclear on where exactly to pick up the o-rings.

Looks like the guy who can't read is hereeeeeeeeeee too.

Just finished replacing my O rings on my fuel fittings. The hardest part was removing the black plastic retainer in the fitting. I used a paint can opener and it worked pretty well. Only problem I had was that when I pulled out the black retainer, it resisted at first, and then "popped" out, and flew across my garage. Luckily, I found it. Putting the new "O" rings in was easy. And, no fuel leaks after re-assembly.
Thanks for the write-up on this...it really helped...

Glad I could help you out Mr. Ghost.

yeah, definatetly don't put so much force into getting the retainer out that you make it go somewhere u cant find. Mine just popped out on one side, so i knew it was close to coming out, so i was gentle working it out. also, it helps to put a giant cloth or something across the top of the engine bay so it doesnt fall down in the engine somewhere

You would be better off switching your lines to stainless.

Wow... I feel fail... I completely missed this thread somehow and the other ones linked (which are failed links now)...

Fortunately when my engine blew last year we put all new o-rings on top and bottom of the injectors... as the tech and I are perfectionists and didn't want any leaks.

Unfortunately I just crested 95k and the fuel rails have been disconnected multiple times (LIM repairs, gasket replacements, new engine, etc...) and the Quick Connect O-rings have never been replaced... someone say a prayer until I get them changed .

I haven't as of yet smelled gas or noticed any leaks and I'm always checking fluids and playing under the hood, so I would notice... altho I DID remove the SC Cover and Hood Insulator, so fumes would probably just dissipate before I ever even noticed them. I Need to look into this

Man, about a year ago today I started smelling fuel and found a leak at the disconnect.
I could not locate o-rings anywhere at all, no luck whatsoever.
I ended up buying a kit at harbor freight of lots of random sizes, and ended up finding the right sizes in there.
It was a huge pain to get them out, and even worse to get them in.. but I did it.
