Key Features & Customer Benefits
- OEM Spin‑On Design – Ensures a precision fit and straightforward replacement during scheduled service intervals.
- Water‑Stripping Media – Reduces water contamination risk to the fuel injection system for prolonged injector life and consistent temperature control.
- High‑Capacity Filtration – Traps fine particulates to maintain fuel efficiency and protect high‑pressure pump components.
- Corrosion‑Resistant Canister – Withstands transport refrigeration environments, supporting dependable operation in Amarillo, Lubbock, Odessa, and the Permian Basin.
- Fleet Uptime Focused – Minimizes downtime and service events to improve return on investment for refrigerated fleets and temperature‑sensitive logistics.
Product Details
| Part Number | 904175 |
| Product Name | Kit, SGCO4000 Secondary Fuel Filter |
| Type | Spin‑on secondary fuel filter (canister style) |
| Function | Removes water and fine contaminants from diesel fuel prior to injection |
| Compatibility | Thermo King SGCO‑4000 generator sets / TK DV6 4‑cylinder diesel engine applications |
| Manufacturer | Thermo King (OEM) |
Efficiency & Sustainability
This secondary fuel filter improves fuel‑system efficiency by preventing injector fouling and maintaining clean combustion in transport refrigeration engines. By reducing fuel system wear and optimizing combustion, the filter supports fuel‑efficient cooling and lowers lifecycle emissions. The component integrates with Thermo King control and refrigeration platforms — from Diesel Direct Electric installations to Smart Reefer SR‑4 equipped fleets — to meet modern temperature control demands while supporting CARB Evergreen‑aware maintenance practices.
Installation & Maintenance Tips
Follow OEM service procedures: isolate power and fuel supply, place a drain pan, remove the spun‑on canister to drain residual fuel, clean the filter head, lubricate the replacement O‑ring with clean engine oil, and hand‑tighten the new filter until contact with the head. Prime the fuel system to remove trapped air. Use genuine Thermo King replacement parts and approved clamps to ensure secure fitment and reliable service intervals.
Real‑World Applications
This filter kit serves refrigerated trucks, reefer trailers, and transport refrigeration generator sets that rely on the SGCO‑4000 engine family. It supports continuous temperature control during door cycles, long hauls, and Permian Basin operation where fuel quality and uptime directly impact cargo integrity and delivery schedules.
Available for installation and service in Amarillo, Lubbock, Odessa, and throughout West Texas.
