Catch can tubes imploding

I bought a catch can for my Hemi and installed it yesterday. When i got home i popped the hood to look at it and both the input and output tubes were impoded like all the air was sucked out of them. Is this normal? The tubes are about 2 feet long.

Which catch can did you install? What type of hosing? Use emission/fuel line hoses.

Thanks for the quick reply!

It's a Weapon R Aluminum Billet Oil Catch Tank - Universal

The hosing looks like beverage machine hosing for those pop machines. Is this going to harm anything or start throwing codes?

Make sure it's vacuum hose. Any parts store should have it.

Marine fuel hose (Type B) will not collapse under slight vacuum and is oil-resistant.

Verify that there is no plugging and your PCV valve is operational. The vacuum should not be that large. Also, check your catch can to ensure it is flowing air. Probably is since both hoses were collapsed.

My vote is for stiffer hoses also.
