Fuel Tank Filter (Part No. RG518-51130)
Description
The Kubota RG518-51130 Fuel Tank Filter is a genuine OEM fuel filtration component designed to protect Kubota diesel engines by filtering fuel directly at the tank outlet before contaminants enter the fuel system. Engineered to Kubota’s exact specifications, this filter captures dirt, rust, sediment, and other debris, helping maintain a clean and consistent fuel supply.
As a result, it helps protect fuel pumps, injectors, and fuel lines from premature wear and contamination-related damage. Furthermore, cleaner fuel promotes smoother engine operation, improved combustion efficiency, and more reliable performance in demanding construction and utility applications.
In addition, the RG518-51130 functions as a critical first-stage fuel filtration component, helping prevent larger contaminants from reaching downstream filters and injection components. Consequently, it supports longer fuel system life, reduced maintenance costs, and improved equipment reliability.
Built to genuine Kubota OEM standards, this fuel tank filter delivers dependable fitment and long service life. Therefore, whether used during routine maintenance or as a direct replacement, it provides the filtration performance required to keep your equipment operating at peak efficiency.
