is the tube that runs from the carbon canister to the purge valve uninterupted.

What is your question?

Is it OK to disconnect at the rear of the car where the carbon canister connects to the under body tube and at the purge solenoid at the engine to use shop air to clear the tube before installing the new solenoid to prevent any carbon particles from plugging up the new solenoid and prevent it from getting plugged again as a precaution.
