Catch Can Installation Help

I bought a BWoody Universal Catch Can recently, but I'm having an issue with the installation. The valves on the can need 3/8" fuel line,but the valves on the PCV are larger in diameter. This seems to me to be a simple problem, but I am not sure how to approach it... I just thought it would be better to be safe than sorry!

Thanks in advance!

You can get adapters to downsize the pcv hose to the can.... but would that not beg the question of is the higher pressure of the smaller line going to be bad for the engine? The purpose of pcv is pisitive crank ventilation, its supposed to release pressure into the vacuum of the intake. Narrowing that hose might not allow it to release enough pressure in high rpm conditions.
