Default Injector O-rings

Since I couldn't get my daily fix here for the last couple of days, I was poking around on ClubGP and saw a number of posts about leaking injector O-rings. Several people'* cars went up in flames and were total losses. I had heard other references to L67 fires on a Camaro board but I never knew what the source of the fires was.
It sounds like this is an L67 issue and was wondering if others here had experienced the same thing. Assuming this is something I shouldn't take a chance on, I'm thinking I should tackle this at the same time as the manifold gaskets.

I haven't heard of an issue with leaking injector o rings.

Although if you had them, it would usually be noticed in the performance of the car.

It may come from people doing a poor job at injector swapping or taking their injectors out to clean them and having old rotten rings without replacing them. I would not anticipate this problem on a stock motor.

As well..each time I pull a fuel rail that'* been in for more than a month...I change the o rings. They are cheap, easy to do and worth the little expense and time.

It is a no-brainer to change injector o-rings when doing work where injector rail is removed. They are inexpensive and provide good insurance against future leakage.

how easy is it to remove the rails and replace the o-rings?

my car is a '01 GTP with 73k miles.

Remove electrical connectors from the 6 injectors, undo the 4 or so 10mm holding the rail down...wiggle and pull up. Remove and replace rings from both ends of injectors. Lightly lube with vasoline to make them go together nicer and reinstall.

As mentioned, it sounds like it is a no-brainer to do them. However, in looking at the ClubGP posts, there seemed like there were a very large number of fires in the GTPs leading me to wonder if we are vulnerable to the same thing or are there some differences between the SSEis and the GTPs in the way the fuel line connects to the fuel rail that would mean we don't have the same potential for a fire?
