Yes it is the vac hose...does the Skoda standard resemble an uprated dump valve but is just a bit smaller? The one in my car is black and metallic.

The vac hose sucks air so as Chicken says just put a cable tie round it, that's what i have on mine and it's fine. The standard one is a smaller black one

Thanks to both of you for your help.

No probs m8, if it's still too quiet for you fit a cai, sounds just right with one on.

The standard Skoda one is smaller and black but it's plastic rather than metal.

Thanks for the pic looks like it...

Did the Compbrake Dump valve fit far easier than expected...there was oil? in on the connector that does into the air box pipe...is that normal. The dump valve I removed was the standard one.

How often do I have to service it and how? I took the car for a test drive and did not notice much difference...the ****st sound was also quite pronounced as well is that normal?
