The Haynes manual I have says the fuel pressure regulator is with the fuel pump on the rear bulkhead yet someone I thought was pretty sharp pointed out what sure looks like a regulator under the hood on the passenger side of the engine. I'm told the best way to drain fuel is by a hose on the regulator and using the pump?

I've also read somewhere that even with cars having overturn valves it's sometimes possible to snake a hose down the filler neck and use a good old gravity siphon. Is this possible on a Miata?

Probably from a few years driving a gas tanker and hearing every story ever told about bad happenings with gasoline I'm probably a bit paranoid about using anything that may spark around gasoline.
