Sounds like you know more than me at this juncture. Your guess makes sense. You should probably cross-post this in the 2001-and-later forum, good chance someone there knows the answer.

Well I took out the o-rings and put them back in and still leaking around where the hose connects into the firewall.
I took a few pics the best I could, it was hard getting my phone close for good shot, but maybe yall can see what I'm talking about.

Would a bad coupler be leaking like this, it didn't leak before when the old hoses were on?
