Re: Draining gas tank

["Wm. Josiah Erikson" <josiah@gsinet.net>]

Did you take the filler neck cap off? If you didn't, the gas would have a hard
time coming out. Normally, when the fuel pump is pumping, it's pumping it out of
the tank and most of it is going back in again throught the return line, so you
don't really have a vacuum issue.
