Draining Gas Tank?
Draining Gas Tank?
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

You can drain it from under the front bonnet.
There are (4) nuts on top of the gas tank that removes the "inspection lid",
be careful with the stuff attached and it can be set aside for easy siphoning.
