Hey everyone just wanted to drop my growing parts list that fit my 91 S82P Truck, it may be of help to a few of you guys out there. BTW I've got the EF-CS Motor Air Filter - WIX 46677 (Just had to poke a hole in the middle rubber end of the filter for the mounting thread that holds on the air box cap to fit, Super simple). Oil Filter - WIX 51394 Fuel Filter - I gotta find the number still, but WIX has one that clamps right into the OEM location with the 90 Elbow in it. I'll include a picture for an idea.
