The protective casing has a base member with a first end and an opposite, second end and a pair of opposing side members extending from the base member in a first direction such that the base member and the side members define a cavity. The side members define a channel through which the hose passes into a cavity such that hose is received in the cavity and the gauge is positioned at the first end.
