Its fairly low pressure, just take lines off and plug with bolts. I don't do that. I usually just put "Stabil" in the full tank and ride it for ten minutes or so and then just turn off petcock. "Stabil" will keep the gas good for 6 months. The full tank keeps condensation from causing rust to a minimum.
