The car smells of fumes all the time it's driven. Other than finding a new cannister, has anyone come up with a solution? No Stock

You need to figure out which line hooks the highest in the tank, not perfect but better than the pressure you are building now. That only works if the other valve cover breather is connected to the engine air filter or carb. If he has an open breather on the other side he will still get the fumes.

The 2 and 3 nipple breathers have a large nipple that must be hooked to the air cleaner, the other side must have a working pvc valve. You MUST make sure the tank line does not leach raw fuel into the motor, crankcase explosions, diluted oil can result.

With the stock cap, on cool days I was getting vacuum building up in the tank from no vent and the fuel pump drawing out of the tank and on warm days I would get pressure in the tank.
