I was changing both the primary fuel filter and chassis filter on my 6.7 Cummins
When I was installing the new mopar primary fuel filter the paper media bumped along side the engine and left a black smudge. Normally it wouldn’t concern me if the fuel was filtering from the outside of the filter to inside but I am wondering if the primary fuel filter filters from the inside out? If that’s the case there’s a dirty smudge on the outside of the paper media
I don’t see how it’s possible to get the primary fuel filter in without bumping something along the way.
And if it is filtering from the inside of the fuel filter to the outside, should I be concerned about contaminating my fuel system?
