My 99 S70 AWD has an issue with fuel smells after filling up which is similar to the 96 850GLT I had. You can smell the fuel in the cabin and outside when the tank is full. Once the car has been driven to the point that the fuel needle just begins to fall - no smell at all.

This past weekend I filled up the S70 before traveling out of town on business. I was amazed when I got home four days later and could smell fuel up to ten feet away from the car. Never a leak on the drive way and fuel smell only when the tank is absolutely full.

I have looked under the car (no disassembly) and do not see any signs of fuel leakage on the filler hose or tank. I really would like to get this fixed, but would like some advice from the board as to the best place to start and what products can be used to seal the tank.

The 850GLT had a very similar issue and went to the dealer no less than ten times but the issue was never resolved. I would like to attempt this repair before I start that circus again.

Thank you in advance.
