I am just curious, When this occurs do you have to replace the Rail's or only the lines, injectors, and other effected parts? I have never had one apart so I don't know if you can simply clean the rail's or not.
Not quite the same but on my previous Jetta, I had a CP4 go bad and it contaminated the injectors, pressure regulator, filter housing. Was able to clean it up but had to replace two injectors because I couldn't get them to run right even after disassembly and cleaning.
When we have one come in the shop with a failure, we replace everything because I don't want a customer having another failure down the road because we cut corners. I'm sure most of the time you can get by with replacing the pump and cleaning everything out, but it isn't worth the risk of leaving someone stranded or upset that things weren't fixed right the first time if it doesn't work out.
Yeah, That makes sense. I just wasn't sure if the rail was easy to clean or what.
I know I was told the feed Line can have sealing issue's as well as when you get a failure the line could rupture later on or the shrapnel could embed it self in the line. I am told it's like a Shot gun blast in the high pressure fuel side when a CP4 failure occurs.
Either way it's obvious you wouldn't want to be left stranded on the side of the road because you didn't replace 1 potentially contaminated piece.
Has anyone ever seen debris in the tank? I have yet to find any in the tank itself.

Never looked in the tank though.
