Just in case anyone has this issue also, It is fixed.

The fuel tank vent valve is in fact in the engine bay. Mounted just behind the alternator with the small black lines going into it, one electrical connector. One line goes to the intake boot, the other comes from the Evap canister from the front compartment. Inside the evap is the charcoal filter, a valve and a small pump. The charcoal filter has two lines going into it from the bottom, one directly into the top of the gas tank, the other leads down and back to the vent valve in the engine bay.

My vent valve was stuck open causing the "leak" in the system. I removed it and could blow through. I dismantled it and found some debris in the valve assembly, cleaned it and reassembled. Now it is normally closed and opens when 12 volts is applied.

All errors are gone and system works fine.
