WUR thingy

I am posting a pic of a bit I can't work out. It sits between the WUR and the fuel head inlet that controls the pressure on the metering piston. This apparatus does not appear in my CIS schematics, nor is it on my SC's. So, maybe it is unique to the 930. Because it sits in between the two bits that control the damping pressure I am suspicious if this may be the problem. If I knew what it was supposed to do I could check it. It has a tube out the base - but there was nothing hooked on the tube. Maybe it is supposed to have a vac line, and open some controller diaphragm inside under deceleration?
In which case I may have solved the problem.
The skinny line goes on to the fuel head directly on top of the metering piston, the fat line comes directly off the WUR. I am hopeful the problem is here - if only I knew what it was.
