I'm referring to the system that traps the gasoline vapours from the tank, stores it in the charcoal canister, and then uses it up.

Anyhoo, service manual says to test the system, remove the fuel filler cap, blow into the line that goes to the tank to check that there's no obstruction (i.e. that air can be blown through), and blow into the line that goes towards the engine, to make sure there's no leakage.

Well, when I blow on either hose, I can't blow into it. What could be wrong? I wonder if this is why there's "excessive" pressure buildup inside the gas tank, as it can hiss for 5 or 6 seconds as I remove the gas cap for refuelling. I am also suspecting that this might be causing my hard start problem, which only happens when the engine is "luke warm", and takes 8 or 9 cranks before the engine rotates without the assistance of the starter.

Help?
