Rust in upper fuel filter bowl...what should I do?
So I changed my filters last week on my new to me 2008 F250 (140k miles) after I purchased it and noticed some discoloration at the bottom of the upper fuel filter housing. I didn't think too much of it while changing the fuel filter until I read a post with some information about the discoloration being rust and it lead to $8k in HPFP and injector repairs.
What can I do to at least keep it in as good of condition as I can from here on out? Do I need to do any other maintenance such as some sort of fuel system flush? If I have all the water out of the separator, can anymore be sitting somewhere in the fuel system that cannot work its way out?
I have already replaced both fuel filters and pulled the low pressure pump, cleaned it thoroughly, and replaced the drain valve. There was one little particle in there that I siphoned out while changing out the upper filter.
Any ideas would be great! Ugh, now I'm stressed out...
