Here's a really bad pic, but this is on the back of the engine, on the passenger side, just under the inlet.



The top one goes to the Fuel Pressure Regulator, and the bottom one to the BOV. Hope that helps. :)

By 'pot on the inner wing' do you mean the carbon canister, or are you talking about the boost sensor?
Both of them are meant to be there, but neither of them are totally necessary.

This doesn't really help, but I'm still looking for the diagram you're after:

This is about all I could find on the carbon canister.

I can't look at mine at the moment, but I'm pretty sure it's three hoses: a vacuum line off the bottom of the manifold (to suck the gases through); a vent from the tank; and one that just vents under the car somewhere.

If the car is running I wouldn't worry too much. The vacuum line can be blanked or used for something else, and you can just vent the fuel tank underneath the car (where it would go anyway) - after almost 20 years that carbon canister isn't doing much any more.
