The kit combines a 6-foot rubber hose rated for ethanol-blended fuels, a molded primer bulb to improve fuel flow and starting, and corrosion-resistant steel clamps to secure connections. Components are selected to resist leaking and hardening under normal marine and storage conditions when cared for correctly.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the primer bulb improve engine starting?\u003c\/h3\u003e\n\u003cp\u003eThe molded primer bulb creates suction to draw fuel from the tank into the carburetor or fuel pump, reducing crank time and helping engines fire more quickly. Its design promotes steady fuel flow without excessive pressure spikes, making it especially useful after long storage or when replacing lines.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePositive one-way valves reduce backflow and maintain fuel in the line.\u003c\/li\u003e\n  \u003cli\u003eBulb shape and material support repeatable squeezes without cracking.\u003c\/li\u003e\n  \u003cli\u003eEasy manual priming avoids repeated pulls on choke or starter.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs this fuel line compatible with ethanol-blended gasoline?\u003c\/h3\u003e\n\u003cp\u003eThe rubber hose in this assembly is formulated to accept ethanol-blended fuels commonly used in marine and recreational applications.
