Just tighten up all the hose clamps related to those two hoses. Snug them up good, but don't over-tighten. You'll know that you over-tightened when the worm gear skips a tooth. If that happens, it's time to get a new clamp, which can be found at any hardware store. Luckily, this style of clamp can be completely opened up to be removed/installed around the hose without disconnecting the hose, so it's not that big of a deal if you have to replace a clamp.
Just checked my clamps..i was able to tighten them 2 rotations.. they were a bit loose. Whats that breather you have hooked up to?
