On my old 5000, that had this exact problem, I've cut it into the main
vacuum supply line.
I used ANY cheap fuel filter ($3 avg), that had:

1. matching inlet and outlet dia to couple it with the cut vacuum line.
2. a transparent plastic body so you'll see when it accumulates enough
oil to be replaced.
3. the inlet would be picking up from it's bottom, whereas the outlet
exited from the top. This leaves the oil trapped. That's why I did not
like to use a cylindrical VW (Bug) filter, that most Audisti use for
this purpose - it has both inlet and outlet in line.

There is a number of toyotish or hondish fuel filters with the above
said parameters in any Pep Toys.

Directly behind the glove compartment.
