Inspection pit mystery pipe(No Nazi content)

Cleaning out my inspection pit prior to giving the covering timbers a coat of preservative I came across this metal pipe sticking out of the brickwork, a 90 degree bend facing downward. Any idea what it would have been for? Maybe it leads to a vent outside and it is there to get rid of any fumes from spilt oil or petrol?

Have you got a friend with a long stick and a lightbulb?

Pic of said pipe, probably 1 1/4’’ od if the rust wasn’t there, located about 6’’ down from the garage floor.

It's a breathing tube for when the pit fills up with noxious fumes.

Dispensing pipe?
