Tough place  :) car runs OK  without it, but I must put it back
Perhaps someone has a picture of the place?

If it runs OK at the moment, that suggests that it connects the purge valve to the charcoal canister behind the front right wheel arch.

Expect it to run badly when the ecu opens the purge valve as it will effectively become a massive vacuum leak.

I found the input for it behind the engine near the coil, now I can't find where to put the other end, is it in the firewall below heating pipes?

Offside front wing below the brake servo. Behind the fuel lines where they come through the wing :y

On a rhd car yes. Probably not below the servo on a lhd car, but easy enough to look on the other inner wing if not.

Good point well presented  :D

Right hand inner wing behind the fuel lines...

Charcoal canister lives at the back of the right hand wing.
If you can't see where it goes, then either wheel arch liner or wing off... Can't miss it  :y

Found it, solved. Thank you guys very much, its simple when you have someone to tell you how to. Its a tight place, plus I have lpg vaporizer above fuel lines. Its a black car so I need 5 min to just stare under the bonnet so I can start seeing different things :).
Thank you Doctor Gollum and Mig V6

Car still running rough on petrol, is there a possibility that still has air trapped in the fuel system? When on LPG it runs normal, but on petrol very rough idle

Good point, I have the car less than a year, have no idea. I m changing oil tommorow, so I guess I will change that filter also. It ran Ok before the hose fell off

Well, I connected the pipe on one end at the wheel arch, plastic tube between fuel lines,  other end at the empty rubber hose behind the engine, length of the tube was adequate. Its a petrol problem becose on LPG runs good. Its not such a problem since car runs about 4-5 minutes on petrol than goes on  LPG.. This afternoon  I m changing oil, I ll connect it to computer to check for faults
