I wrote in about OEM vs aftermarket.  I really don't know if I need to replace the tank.  It
doesn't leak, except that we get the gas smell right after a fillup, which I understand is the
top grommets.  However, there are a couple of other problems.  We run out of gas after using
about 13 or 14 gallons, and, at that time, the gauge reads about 1/4 tank remaining.  I can't
see the underside of the tank, because a PO covered it with carpet padding and some sort of
rubber floor mat materal.  I plan to remove that in the next few days and see what's up under
it.

Thanks,
