A tank sprayer includes a tank configured to receive fluid through an opening in the tank, a removable cap covering the opening in the tank, and a removable pump. The removable cap includes a first handle extending outwardly from a first side of the cap, a second handle extending outwardly from a second side of the cap opposite the first side, and a funnel provided between the first handle and the second handle. The funnel has a substantially conical sidewall and a drain leading to the opening in the tank. The removable pump engages the drain of the cap, wherein the pump is operable to advance air into the tank to pressurize the tank.
