'88 90q part #: ques.

[jDolan]

I'm having some fuel problems with my tired 90q. It seems to be fuel
starved, and the intensity of that condition is intermittent, mostly
occurring at startup, and improving somewhat after warm-up. It seems to
be progressively worsening, and now that I remember it, it was there,
only to a lesser degree, last fall before I replaced the fuel pump and
filter after the FP died.
 So, I'm on a quest to figure this out, and without the benefit of a
Bentley's. I consider if could be the regulator(?) thing back next to
the fuel pump? I pulled the intake this AM and cleaned that and the ISV,
also inspected all hoses for cracks, etc. checked tightness of (new)
valve cover gasket, everything I could think of. Nothing found, nothing
improved at re-assembly.
 If anyone has any pointers to throw this-a-way, I'd gladly receive
them. The problem mimics a stuffed filter, is there more than one in the
system? The inline gauze filters at the banjo bolts are very long gone.
And what is the filter-looking thing that sits atop the air cleaner box,
next to the fuel distributor? 3 fuel lines going into it with a vacuum
fitting to the airbox itself, and it has this written on it:
Bosch
0 438 161 016
034133534F

It has this on it as well:
747      (050)

What is that? Is it a filter or some sort of control for pressure? It is
inline with the return to the tank. I removed it, just to check it out,
and it does not easily let air through with gentle pressure. Should it?
Could it be my problem. It might be original equipment, for all I know.
Anyway to check it for function, and is it a normally replaceable part?
Its been there, just fine and dandy for the past 150K miles I've had
it.  ???
