REplacing fuel filters

I stand corrected by a quick look at the family album.  The tray appears
to be "hard mounted" to the chassis, and all the parts it holds are
mounted with rubber bushings one way or another.

Here's a synopsis:

443 133 741 A - pre filter mount (to chassis)
443 133 741 A (2) - accumulator bracket mounts
431 906 095 (2) - filter bracket mounts
803 121 275 A (2) - fuel pump bracket mounts.

since these mount the brackets to the tray, it is possible that the
parts might be replacable wihtout messing with them.  But many old ones
are shot anyway, to take a look first.  I also recommend new nuts and
washers all over these (S/S, of course).  They are all 6mm, one at each
end of most/all of the bushings.

811 201 218 B - accumulator to filter plastic fuel line
853 201 220 A - filter to pump plastic fuel line

hope this helps!

here is a picture of the similar, but different, arrangement on the '89 90Q:
