Recently I've had a fuel smell in the cabin after driving short distances and letting the van sit for about 10-15 minutes.. I'll run into the store and come out and it smells like fuel inside only. Nothing outside. I've read all the threads about the fuel pulsation damper and it's not leaking. Recently replaced the fuel filter and rechecked all connections and hoses, they look good. Filler hose looks good. No leaks under the van or visible on any fuel lines or components I can see. No drop in fuel economy... city only has been 20-22 mpg.

The only thing I've noticed out of the ordinary is what sounds like the fuel pump stays running for about 30 seconds or a minute after turning off the van, but this is only intermittent and I'm not sure that it corresponds to the fuel smell.

I can't find a mechanic in town that knows much more than I do about working on these vans so I'm hoping you all have some suggestions. The van is a 1989 auto with right at 198K miles. I thought maybe the injectors, but again, the van runs great and there's no loss of fuel economy or power. Any help appreciated.
