I assume you've already gone through the phase of throwing parts at it and that it has a new vent solenoid and is still throwing a leak code? I've seen quite a few of those Chrysler fuel pump units break at the lock ring and leak vapors from the top of the tank.

Yup and actually it's an evap code. Good call on the lock ring/seal. Is that something I can check easily? Can I reach or at least see where that lock ring is?
