To install the primer bulb, ensure it is oriented correctly in the fuel line; the arrow typically indicated on the bulb body must point in the direction of fuel flow toward the engine. Secure the connections using appropriate hose clamps to prevent leaks. This unit is compatible with 8mm bore fuel lines. For care, avoid exposure to harsh external chemicals that could degrade the rubber bulb over time. Periodically inspect the aluminium tails for any signs of corrosion or debris buildup to ensure the internal valve remains clean and fully functional.
