Fuel Pump Relay - Jumper- drain fuel tank

[Mig]

My 1999 Boxster project car took s bit longer to complete than expected. Isn't that always the case? The fuel in the tank was 16 months old and I didn't want to take any chances. This write up saved the day. I drained 10 gallons out without spilling more than a couple of drops.

Unfortunately there are several details in that link that do not match my experience with a 2001 S .For example, Wayne wrote :"This will cause the fuel pump to turn on automatically when you turn the key in the ignition." NO it runs w/o ignition switch operated !
The article lacks other tedious practical details that I mentioned. Some of which may prompt you to needlessly buy a new Fuel Pump.

I have a lift so this makes it easy for me but I usually raise the car to the right spot to put a 5 gallon gas can on a chair. My cans all have tubes that loosely fit over the fuel line disconnect close to the rear left tire. I usually disconnect the battery and hook up a battery charger to the +&-. With the battery disconnected and the jumper wire in the relay, I can control the fuel pump by plugging in the battery charger. I'll sit there and watch until the fuel tank is empty. The second I hear/see the tank is empty I disconnect the battery charger.
