The fuel hose features snap-on connectors for quick attachment and removal of fuel tanks and outboard motors. Commonly used as a hand pump on boats for outboard motor fuel supply. The bulb is designed to maintain flexibility and prevent collapse in both hot and cold weather conditions. An arrow marked on the hose body indicates the direction of fuel flow, ensuring fuel travels from the tank to the engine and prevents backflow by maintaining pressure in the line. Installation steps: 1. Remove the female cap from the tube. 2. Press the female cap, align the male connector from the fuel tank, and insert securely. 3. Squeeze the hand pump to deliver fuel to the outboard motor. Constructed with materials compatible with today’s alcohol-enriched gasoline blends. Designed to be highly resistant to ethanol-blended fuels, offering improved reliability and convenience. Made of durable rubber material that provides excellent sealing properties, strong resistance to fuel and air leaks, flexibility for easy bending, and resistance to cracking, abrasion, and corrosion.
