I was replacing the fuel filter, and made a point to note the orientation of the current filter before removing it. However, the new filter has a "FLOW" arrow which, if I install the filter the same way as the current filter, will be pointing toward the rear/tank. This seems wrong, obviously.
Is it possible my filter has been backward for 60k miles? Can the car even run with the filter installed backward? Was I getting any fuel filtration all those miles if it was installed incorrectly?
The filter canister has a rim on one outlet end (based on the flow arrow), and is smooth on the input end. Which way does it go?
