just take the fuel line off the carb and plug it into the pressure fitting on the tank,you'll be ok for one night.the reason I say to loop the line like that is to prevent the fuel from being exposed to any air or moisture,nitro fuel is hydroscopic (it absorbs moisture out of the air) so as long as the fuel is sealed up airtight it'll be fine.(I'm sure it'd be fine even if you don't loop the fuel line,your choice).
