That hose is the fuel pressure regulator.  It is small like 3mm ID.but any
skinny vacuum line will work from the flaps.

Most likely is that you are using more gas then you need
to...........pressure is increased at the injectors, and the electrical
pulse that opens and closes the injectors remains the same.......thus more
fuel in same amount of time.  My  theory anyway...........
