Hi,

I am after a part number for my MY00 UK spec Impreza.
The part is a small black circular rubber/plastic disc, about 4cm diameter in size. It sits in the bulkhead, within the engine bay just below where the filler for the brake fluid. It is designed to come out to fit for example a pipe in from the engine bay to the cockpit for a boost gauge.

If anyone knows the part number it would be appreciated please.
