Welcome

First off, you can check your own codes. See the DTC Sticky at the top of the forum.

Secondly, always post the code definitions. We do not have them all memorized. A link with the definitions is posted in the Sticky.

Third, 30 PSI is rather low. Might check the FPR first. If that is OK, then it's more likely a bad fuel pump as opposed to a fuel filter.

P.S.
The fuel pump is accessed through an access panel in the trunk. No need for a tank drop.
