I just checked the used fittings I have here, and I find a single
sealing washer, between the filter sock flange and the flange on the
outlet pipe. I guess the flange on the sock is expected to deform
enough to seal against the tank nipple. That's also where the
microfilm shows the sealing washer, and it only calls out 1 washer
per car.
Try some nylon washers. If you can't find something exactly right,
buy some with the right OD and use a tapered reamer to modify the ID
to fit. Look at the flange on the filter sock. If it's rough, modify
another nylon washer to seal between it and the tank nipple. That one
will need a larger hole.
