Fast forward to today's post date:
After struggling with this repeatedly in the years since, and smoking the evap/tank system, I finally decided to drop the fuel tank for the first time since the car left the factory (Aug 1997). It wasn't as bad as I'd been told. Frankly, not sure what the big deal was supposed to be?
Nothing jumped out at me. I pulled both the fuel level sender & fuel pump. Both gaskets were OK and original. I cleaned both then lubricated and reinstalled. I noticed a small click-connector that must be pushed forward, then have the retaining clips depressed before pulling backwards to free it. Inside were a pair of o-rings that were quite dry (gray). I was tempted to cut the thing off as I had with a similar connector on the charcoal can. However I'd need an elbow which I didn't have. Instead I cleaned old, hard grease out of it, then lub'd the o-rings with silicone grease. All vapor lines were hard plastic and crimped with Oetiker rings. No sense in messing with that.
I put it all back together, reinstalled the tank and cleaned up. This was back in mid-April or March of this year. Once cleared, the P0-455 code has yet to return! I was cautiously optimistic back in May when it failed to re-appear. Here we are at the end of June. Plenty of time for the ECM to run the EVAP diagnostics test given all of the traffic I have to wade through.
Finally the ellusive EVAP dragon is dead!
