Unhappy P2451 Evaporative Emission System Leak Detection Pump Sense Circuit - Value below low

Hi,
I am debugging a problem with my 2006 Turbo S.

P2451
Evaporative Emission System Leak Detection Pump Sense Circuit - Value below lower limit value, test conditions are not-completed, fault is currently active and causing a DTC light

History:
- I have replaced the EGR valve
- I still get a DTC after 4 hrs of driving...
- I smell fuel vapors occasionally, which seem to be coming from the rear of the car.
- There is no sign of a leak anywhere... I have checked all over.
- I noticed that there is a relief valve on the fuel inlet...

Any help would be appreciatd...

Did you ever figure this out? I'm having the same issue on my 2005 CTT.

Thanks... Josh
