Evap can with 2 sensors? I'm going to be using the evap system to vent my tank. I recently purchased the one below from ebay. It was originally in a Chevy Cobalt. I noted that it has two connectors. What are they? One is surely the vent solenoid, but the other
. I'm guessing pressure sensor??

I would guess that the EVAP system on the Cobalt is like the LS1 Fbodies. One of the electrical connectors is for the valve that opens the EVAP can to atmosphere, the other is the vent to the vapor purge line. You have 3 tube fittings on the can: 1: vapor from tank; 2: Vapor to purge valve on throttle body; 3: Atmospheric vent. Check to see if the pressure sensor for the Cobalt is integrated with the in-tank fuel pump like the Fbody. You will have to have the 2 valves and the pressure sensor functional for the EVAP to work like a stocker. We put our pressure sensor on a "T" in the vapor line to the EVAP can.
