trying to order a crush gasket for the oil strainer on the io-390. The Lycoming parts catalog doesn't seem to show one. Is this a Lycoming error?

AN960-16 ??
yeah, thanks. Looks like the 390 has a couple of additional parts vs. the 360 (items 13 and 15 on the 390 drawing).
For some reason they didn't show the 390 plug and gasket in line with the suction screen like they do on the 360
Has anyone here removed the screen from an IO390? are those 2 parts (13 and 15) attached to the screen when you remove it?
Actually, looking closer at item 15, it looks like an optional plug to replace the standard cap to which you can attach a hose for some other purpose
The applicable parts depend on what variant of the IO-390-A you have, e.g., -A1A6, -A3A6, -A1B6, or -A3B6. See the pics below from the IO-390-A Parts Catalog. But it still doesn't make total sense to me. For the -A3B6 they can't use them all, so the table may be in error. But you'll need the crush gasket.
The broken side of the washer goes towards the stationary part, in this case the engine case. Hand tight and then three flats or 135 degree turn.While we are on the subject, is there a correct way to install the crush washer? Which way does the seam face?
Thanks
