Well, this is getting interesting. Some scavenging through the web indicate that adapter is supposed to have the filter laying sideways facing the firewall. It was the Wranglers that had the filters pointed straight up. The short block came from a 94 Cherokee, but now I think I'm gonna end up decoding the engine number to find out if this is it's 3 vehicle (at least

) it's resided in.
Funny, the Wrangler guys are all eager to get their hands on the Cherokee adapter because of "messy oil changes". Even with mine pointing straight up, I had no problem keeping it SLOWLY spewing into a catch.
