Seems odd it has two numbers but the rest have one single number?? The 3593A looks to be the closest upsize but as mentioned by others why not just use the 9688 spec. Just wanted to know if using up the 7317 was possible I'm still wondering.
Since 13 PSI is about in the middle of the 9-15 PSI range, they are basically the same. If the 7317 physically fits in the mounting location I don't see any reason it wouldn't work.
The base gaskets aren't exactly the same size, but if the filter mount has a decent sized flange it should still work. I'd inspect the filter mount carefully when the filter is off, and put a thin layer of grease on the 7317 gasket and spin it on to just kiss the mount, remove it and see what kind of footprint the greased gasket left to determine if the 7317 gasket size works OK on that engine.
