Re a leak around the fuel pump. Would not this happen ALL the time the car is running (and be quite dangerous)? =
I did not say "leak", I said "seepage" and "stains". VERY LITTLE fuel was escaping, but enough I could smell it at times.
It takes VERY little gasoline to generate an odor.
If its ONLY with a very full tank, I'd suspect the seal around the fuel level/pressure sensing connector (center, top of tank) or the filler neck area.
Im still surprised that the EVAP test is not failing and generating a CEL and code.
