Description
Overview:
The Underside Stay (A) of Fuel Tank is the lower support bracket for Yanmar single‐cylinder diesel engines such as the L100N and L70N. This genuine Yanmar component (MPN 114210-55210) is made from black-painted steel to provide strong, long‐lasting support beneath the fuel tank. By holding the tank firmly and keeping it aligned with the engine frame, it limits vibration and stress on the tank mounts, helping to prevent leaks and premature wear. The stay follows the original geometry and mounting points for a straightforward swap during service or repair. Suitable for plant, generators, pumps, and other equipment powered by the L100N series, it helps maintain reliable fuel delivery and stable operation in everyday use.
