Navistar MaxxForce Fuel Line Disconnect Tool Kit: ZTSE4773 11.8mm (OEM Direct)
The ZTSE4773 Fuel Line Disconnect Tool Kit (11.8mm) is the genuine Navistar International OEM tool for safely releasing quick-connect low-pressure fuel lines on MaxxForce 11/13, DT466, and similar heavy-duty diesel engines—prevents connector damage, clip breakage, fuel leaks, and system contamination during service.
The High Costs of Improper Fuel Line Disconnect on MaxxForce Engines
Quick-connect fuel fittings on MaxxForce 11/13, DT466, N10/N13 engines lock tightly under pressure—using pliers, screwdrivers, or force can crack connectors, break clips, cause leaks, and introduce debris.
- Connector breakage – $200–$500 per fitting replacement
- Fuel line damage – $250–$700 for hose & re-routing
- Fuel leaks & cleanup – $400–$1,500 including contamination
- Downtime & labor – Extra 1–4 hours at $150–$300/hr
- Injector/fuel system damage – $1,500–$5,000+ from debris
- Safety risks — Pressurized fuel spray hazards
