Where is the Fuel Tank Pressure Sensor on a 2 Door!?

[Bull Gear]

After hours of searching I still don't know.
I have the P1441 EVAP PURGE DURING NON-PURGE code on my '97 Tahoe 2 door 4x4. I pretty much ruled out the purge valve, so I suspect it must be a bad tank pressure sensor. I dropped the tank today to replace the sensor and... uh... no pressure sensor. Apparently the 2 doors have the old style TBI type pump assembly. Where in the hell is that tank press sensor. It's gotta have one for OBDII, doesn't it?

Problem solved...
Apparently the '97 2 door Tahoe has a bastardized EVAP system. There is no tank pressure sensor or vent valve as found on the 4 doors. The 2 door has an "Evap Canister Diagnostic Switch" (AC Delco PN 212578) that sits just upstream of the purge valve on the intake. Mine was missing and the numb-nut who preceeded me had the pigtail for that valve plugged in to the hood light. FAIL.
Maybe this will help someone else down the road. I talked to a bunch of people and spent hours searching the net to no avail. Finally called the GM tech line and had them confused for quite some time before we finally sorted it out.
