Any more progress...Reports?

Ran a hose from the filler looped up to the roof and vented it out the bottom of the rear quarter. This Bypassed the plastic tank in the C Pillar and eliminated most of the smell. I added a couple of NACA ducts to vent air into the car.

What did you do for the lines running to the canister?

I left it in place and plugged it.

Was looking over the PET and the way these hoses run is mind numbing! My brain is still hurting!
Got to try and simplify this whole system.

I'd check the fuel return/breather/ fuel level sender -complex at the top of tank. Remove the large plastic collar and lift the thing out of the tank.

It might be that the fuel tank has been collapsed during the years (poor venting and strong vacuum or possibly collision damage?). If this happens it will bend the fuel sender and possibly the fuel return pipe that runs all the way to the bottom of the tank. If the tank deforms it will hit the return pipe at the bottom and force it up somewhat. This will be enough to cause hairline cracks to the soldered return/breather pipe connections at the top of the tank. Small cracks are enough to let the fuel smell out.. No promises but worth a check anyway!

Going to replace sender....not reading accurately.

John, I owuldn't plug them. In case of fire, it will let pressure build in the tank. If the fuel lines under the hood go, fuel will keep spraying, regardless of what you do, until the cap is removed. A very nice Turbo S was lost to a fire at Road Atlanta last year. I don't they couldn't get it out because of this until the cap was removed. Not sure if it would have been salvageable, but it sure didn't help.
