Help on a Sunday!

["Oscar Murphy" <rmurphy@batnet.com>]

Hi fellow Qlisters,

Well, I managed to successfully replace the BomB and a couple of hoses on my
91 200TQ without major hassles. I was starting to feel pretty good as this
was my first attempt at doing some of my own repairs.

THEN IT HAPPENED!!!! 

While connecting one of the hoses to the power steering hydraulic reservoir,
I broke a connection on what appears to be a plastic filter of some kind. 
It sits just below and slightly to the left of the reservoir. One side is
yellow and the other is black. There are 3 connections:
    a) one black tube goes the the back of the intake manifold
    b) one opaque tube (looks pink now, may have been white originally) goes
to the firewall on the driver's side
    c) one black tube goes to the top center of the firewall

I managed to read the part number on it: 893-820-675B.

I've looked through the Bentleys and can't seem to find anything that
resembles it. Any ideas as to what this is? Is it safe to drive the car with
it broken?

Any help would be greatly appreciated.

Regards,
Oscar "The Hamfisted" Murphy
