Draining Gas Tank?

[slant911]

Sounds crazy but what is the best way to drain the gas tank? I don't believe I can shove a siphon hose down in there because of the electronic flap in there would stop it.

I need to do the recalibration procedure for the fuel guage which involves draining the tank then putting in a predetermined amount of fuel before the calibration procedure.

TIA

From the TT service manual:

"It is impermissible to suck out the fuel through the filler neck, as this can damage the inner flap on the filler neck. Always suck out the fuel through the hole for the fuel level sensor."

Loren,

Is the fuel level sender underneath the "service hatch" square thing in the middle of the trunk area?

Thanks.

Item 5 is the level sender

Item 5 is the level sender

remove the battery and battery tray to expose a black cover plate fixed on by M8 bolts i think? four of them. under that plate is the fuel tank sender unit. unscrew the collar and remove sender.

mmmm...That part with it's giant screw on collar is located underneath the "service hatch" on my car. No battery removal required. I think?

Turbo and C4/s in the trunk under the trim in front of the battery, C2 under the battery.

So how do you get that giant "nut" loose? Some gorilla must have put mine on because it ain't budging. Way too big for any wrench that I am aware of. Of course I don't want to break it as it probably cost $500 for that hunk of plastic.

Thanks again.

Had a feeling you might say something like that :)

Are there any alternatives to that "special tool"?

Boxster guy said he got the locking ring off with a screwdriver.

Not sure I want to go the "screwdriver" route. I was looking at one of those rubber strap wrenches. I'll let you guys know if that works.
