Help locating fuel vent Housing on 1999 Cab 6spd

[Pressed]

I'm in my garage getting ready to replace a fuel filler vent valve and Evap Canister. Can anyone tell me where the fuel vent valve housing is located. I figure I would check it to see if it needs some cleaning while I have the wheel and liner off. Any help would be greatly appreciated.

This diagram if for a Boxster, but the layout for the 996 is similar:

Thanks for the diagram , JFP. I was studying this and other emissions diagrams in a quest to help me better understand the system . I have seen diagrams that have the vent line housing included but for the life of me, I can't figure out how it's oriented in relation to the Evap canister. I looked up, down and sideways but saw no vent line housing (This was with the Evap Canister and fuel filler vent valve removed !!!) I almost mistook the door actuator for it but then remembered that the housing contains the evap solenoid and shut off valve. Well, I have already finished placing a new bleeder valve and evap canister in my 99 996 Cab and my GHL motorsport mufflers have been resurrected after months of the car sounding like a coke bottle in the wind (see pelican parts for the symptoms of a faulty bleeder valve). I'm hoping that my cel will disappear permanently after I do a quick disconnect of the neg battery terminal (No diagnostic scanner yet and Getting that notorious P0410 and P1411 codes accompanied by a 1128 y'know?). These codes are indicative of secondary air injection issues but I'll leave that for another post   Thanks again, JFP.
