Missing ?

[williamcharrison]

Hi all I hope your winter was more pleasant than mine. Suffice it
to say that every man over 50 needs to have a regular prostate exam.
What has kept me going is a dream of sunny days and a trip in my bird.

Today's question pertains to something missing. In the left rear
engine access there is a bracket below the oil filler tube with
nothing in it and a black ~5/16" plastic hose with a threaded L-
shaped brass fitting on the end that looks like it used to connect
to something, any ideas?
