The Mikuni Round Standard Fuel Pump (DF52-176) is a proven, pulse-operated diaphragm pump built for consistent fuel delivery in high-demand conditions. Ideal for racing karts, motorcycles, ATVs, snowmobiles, jet skis, and other small engine applications.
This model features one inlet and two outlets with 1/4" (6 mm) slip-on connections, delivering a free-flow rate of approximately 35 liters per hour (9 GPH). The durable round-body design includes two sturdy mounting holes (6 mm diameter, spaced 92 mm center-to-center) for secure installation. Nickel-plated hardware resists corrosion, and the gasket-seat mounting ensures a reliable seal.
