Wacker Neuson 5000173397 1/4 NPT Barb Male Elbow Fitting

The Wacker Neuson is a genuine OEM 1/4 NPT Barb Male Elbow Fitting designed for the GP3800A, GP5600A, GP6600A, and GPS5600A and GPS6600A series portable generators. As a direct factory replacement, this fitting matches the original connector geometry and thread specification for a secure, leak-free installation into your generator's fuel line system. Wacker Neuson genuine OEM parts are manufactured to the same standards as the components installed on the production line, so you can be confident this fitting integrates correctly with your existing fuel routing. Whether you're completing a routine service or replacing a damaged fitting, part number is the correct choice for these GP and GPS series machines.

Key Features

• Correct Thread and Barb Specification — 1/4 NPT male thread and barb dimensions match the original fitting exactly, ensuring a proper seal without thread damage or fuel line distortion on installation.
• Genuine OEM Component — Sourced directly from Wacker Neuson, this part carries the same material grade and dimensional tolerances as the fitting originally installed at the factory.
• Broad GP and GPS Series Compatibility — Confirmed fitment across the GP3800A, GP5600A, GP6600A, GPS5600A, and GPS6600A portable generator lines, including CARB GFI and wheel kit variants.
• Elbow Configuration for Tight Routing — The 90-degree elbow profile allows fuel line connections in confined generator housings where a straight fitting cannot be routed cleanly.
• Fuel System Integrity — A failed or cracked fitting can allow fuel to weep or spray at the connection point; replacing with part 5000173397 restores a fully sealed fuel circuit and keeps the generator running safely.

The 1/4 NPT Barb Male Elbow Fitting is a small but critical connector in the generator's fuel delivery circuit. It creates a right-angle transition between a threaded port — typically on the fuel valve, carburetor, or fuel filter housing — and a flexible barbed fuel line, directing fuel flow without kinking or stressing the line. When this fitting cracks, strips, or seals fail around it, fuel can leak at the connection point, causing hard-start conditions, fuel odor, or a potential fire hazard; replacing it promptly restores a properly sealed fuel path and allows the generator to run at full rated output.
