My truck has the Paccar cartridge style fuel filter, normally I change it around 7,500 miles because it get pretty dark. The last two times I noticed a few metal shavings. These pieces I find are sliver like and not like flakes or chunks. Could this mean anything other than the filter is doing it’s job?

Metal shavings in your fuel filter could mean that your fuel pump is starting to fail, you might want to have a good Tech look at it before you contaminate your fuel system.

Thanks! I guess I better plan on a couple days off and get it checked.
