Water In fuel

[lazydawg]

Just wondering where all the water is coming from in my fuel. I have a fleet of trucks and my 2008 550 is the only one that has a continous problem with water!!! The dealership has replaced the entire fuel system twice

Any Ideas would be great

Thanks

Comes from the source!! Try a more reputable fuel center, paying a couple extra cents for cleaner diesel is well worth. Especially in the 6.0s and 6.4s with their picky injectors. Also drain the fuel filter more often. And maybe install a supplemental fuel filter before the stock ones. I know a lot of guys who did this it's a cheap fix and a necessity if the area your in just doesnt have good diesel

You could also have a buildup of gunk on the WIF sensor that would throw false light.
