Hi all

which is the correct position of this hose ?

FUEL HOSE | Flickr - Photo Sharing!

is a vent hose gas?
This tube is inserted in this hole?

Must also be necessary of a rubber ring around the hose and metal part of the car ?

thanks

yes to everything. Without the rubber grommet the hose will be loose and also let exhaust fumes in.
