it is really hit or miss...some trucks dont have problems and some do. I am hoping mine will either go soon or never since my 7 years is almost up...i have one more year on mine. I have only like 64,000 miles on my truck. I have been running stanadyne almost every tank and added a pre-oem filter/water separator. Only time will tell.

Mine lasted 100k miles. I believe that using an additive helps them last longer and clean fuel I'm sure helps just as much. Balance rates seem to be better for some reason when I use additive vs when I don't, not sure if that means anything for longevity though. So basically if you go for it, make sure its been taken care of and continue from there.

Ive got 160k on mine now...what are the tell-tell signs for when they fail? Leaking? Rough idle? Loss of power? CEL? Just want to know what to look for...looking like Im getting close.
