Cat filters/Detroit engine

This is why I don't care for Fleetguard fuel filters.



This is from a FF5320 2 micron Fleetguard filter.

The same Cat filter 1R-0750 or the larger 1R-0749 have aluminum tops and plastic center tube so they can't rust.

 

How long did the truck set? Where was the fuel from? Where did the water get into the system 2 micron had to be up on the eng and also the secondary filter. I have seen this befor but only when left in the side box whte no wraper.

 

How is the water getting to your secondary filter?

 

I didn't take the pictures. Their from a different forum discussing fuel filters. It was mounted on a Dodge pickup as a secondary between the factory filter and the injection pump. I'm sure the fuel was bought from several different places since it was a daily driver. Either way this can't happen with a Cat 2micron filter since it's plastic/aluminum.

 

Your right this cant happen with Cat filters and i use them . i used Fleetguards for many years and have never seen them rust like that.
had the owner of that Dodge been useing an alum/plastic filter like a Cat he wouldnt know he had a water in fuel issue until he started dropping injectors. a positive or a negative????

 

well neither are a plus but if I have a choice I'll take the water over the rust. The truck this came off of was a common rail so water is going to do less damage at 26k psi than rust, but neither are good.
