2005 Pontiac Aztek Question: where is the fuel pressure sensor located on the aztek

Fuel pressure sensor usually located at top of fuel pump assembly. I wouldn't expect this to be problem though even with check engine results given that problem. Sounds like a leak in evaporative emmissions system. Maybe hose or purge valve problem.
