I own an 03' Spec V. I had to swap out the original tank due to a leak caused by rust. We couldn't find a matching tank at the time so we fitted a slightly different tank and the car ran fine. However, the tank began emitting gas fumes. I also was reading a P1419 code on the OBD. My local mechanic pointed to a missing hose on the driver's side rear as the culprit. It's right behind the rear driver side wheel. I'm not sure what this missing hose is meant for nor what it looks like. Can anyone give some insight?
