If the vacuum side is not being used, try connecting the inlet and outlet with a short length of rubber hose. That may quiet it down.

It may not be possible to get rid of the bubbles in the filter bowl. If all your connections are air tight and there are no pinholes in the gas line, it's probably bubbles forming in the gasoline. My car has a Carter glass filter bowl right at the carburetor. It is full of liquid sometimes, but after driving around, it usually isn't. It's often half full or so, and gas seems to dribble in erratically. The car runs down the road OK. Be sure your gas cap vent or any other fuel system vent is totally clear. Anything that causes lower pressure in the fuel line will aggravate the bubble condition. Hot weather and high altitude will make it worse. "Winter Blend" gasoline will make it worse. Some localities are required to sell "special blends" of gasoline, and some of these may be more troublesome in older systems than others.
