Description
Overview:
This gauge pipe is a rigid metal fuel line for Yanmar single‐cylinder diesel engines, built to carry fuel reliably between system components. It is made from durable, corrosion‐resistant tubing with pre‐formed bends and end fittings to match Yanmar geometry, helping to prevent leaks and air ingress. Supplied under Manufacturer Part Number (MPN) 114250-55150, it fits engines such as the Yanmar L100AE and L48AE commonly found in compact construction equipment, generators, water pumps, and garden machinery. Replacing a worn, kinked, or corroded pipe restores steady fuel delivery, supports easier starting, and helps maintain consistent engine performance. The precise form factor allows straightforward installation without modification, making it a practical maintenance item for keeping Yanmar fuel systems operating as intended.
Key Features:
- Direct-fit fuel line for Yanmar L100AE, L48AE and related variants listed below
- Rigid metal construction for strength, heat resistance, and vibration stability
- Pre-bent to Yanmar specifications for accurate routing and secure seating
- Helps maintain consistent fuel flow and reduces risk of leaks or air ingress
- Resistant to diesel fuel and typical operating conditions for long service life
- Suitable replacement when original pipe shows cracking, corrosion, or deformation
- Straightforward to install with standard hand tools; no modification required
- Identified by Yanmar MPN 114250-55150 for easy selection and parts referencing
Typical Applications:
Used during routine servicing or repairs on small plant and machinery powered by Yanmar L‐series engines. Common scenarios include resolving hard starting, addressing fuel seepage, curing air entry into the fuel system, or restoring correct routing after damage. Suitable for generators, water pumps, light construction tools, compactors, and similar equipment that rely on steady diesel fuel delivery.
Also known as:
Fuel gauge pipe, fuel line pipe, diesel fuel pipe, engine fuel pipe, gauge line, fuel feed pipe. These terms are often used interchangeably to describe the rigid fuel tubing that links components within a small diesel engine's fuel delivery system.
