I recently had a similar problem with my '88. I replaced all of the o-rings and still was still getting high on the fumes! It appeared to be leaking from the rail when in fact, a couple of the injectors were actually bad and were leaking from the pinhole near the top of the injector which is near the rail so as to give the illusion of leaking at the rail. A quick trip to my local u-pull it yard for a couple of replacement injectors and presto! No more fumes. Until the front seal on the transmission began leaking onto the exhaust! Good luck.
