[FrickingReallySlow]

I installed a catch can from the earlier this year and just noticed that the outlet hose that goes from the back of the block to the catch can has pretty much collapsed (see pictures). This sort of intakes that somehow there vacuum inside the block?! or the heat somehow got to it? The hose from my catch can to the breather port of my Edlebrock SC is fine.

I bought the braided reinforced vacuum hoses at the same time and just cut it into 2 pieces. DID I BUY THE WRONG KIND?! I checked the catch can and there a little bit of oil as expected. When I installed the catch can I removed the bronze filter and replaced with steel scrubbing pad to allow better flow. I don't feel any issues or CEL but something is definitely wrong if the PVC hose collapsed. Previously without the catch can the hose provided by edlebrock worked perfectly.

Let me know if there a specific vacuum hose I need that for this application many thanks
