Description
Overview:
This Fuel Tank Damper is a non-genuine replacement part for Yanmar single‐cylinder diesel engines, designed to replace OEM No. 114250-55201. Made from tough, vibration‐absorbing rubber with a metal sleeve for support, it sits between the fuel tank and the engine bracket to isolate vibration. By reducing movement and shock loading, it helps protect the tank, brackets and fasteners, supports smoother running, and can reduce noise. It is suitable for a wide range of compact machinery powered by Yanmar L‐series engines, such as generators, pumps and construction equipment. Ideal for L40 and L48 applications, it is also used across other listed L‐series models where the same damper specification is required. A straightforward, like‐for‐like replacement for worn or perished mounts.
Key Features:
- Non-genuine replacement for OEM No. 114250-55201, offering reliable performance at a sensible cost
- Rubber isolator with internal metal sleeve to control compression and prevent over‐tightening damage
- Helps reduce vibration transfer to the fuel tank for smoother operation and improved stability
- Assists in preventing tank fatigue, bracket cracking and fastener loosening over time
- Resistant to diesel and oil splashes commonly found around small engine fuel systems
- Simple to fit with basic hand tools; replaces old or cracked dampers on compatible brackets
- Suitable for use across multiple Yanmar L‐series engines to standardise maintenance spares
- Compact cylindrical form for a neat fit within tank mounting points
Typical Applications:
Used on generators, water pumps, pressure washers, plate compactors, tillers and light construction machinery fitted with compatible Yanmar L‐series engines. Ideal where vibration control is important, such as mobile or site equipment, to protect tanks and fittings and maintain consistent engine performance.
