Dorman 904-484 Quick Disconnect Tool

Dorman Quick Disconnect Tool for Fuel Lines

The Dorman 904-484 quick disconnect tool is built for separating fuel line fittings with a simple press-in action. It helps reduce repair time and lowers the risk of damaging fuel system components during service.

• Fuel line disconnect tool with a 5 mm connector size
• Plastic construction with orange color/finish for easy identification
• Fuel line capable; not for transmission, hydraulic, or A/C lines
• No case included
• Direct service tool for fuel fitting removal on select GM trucks and vans

Fuel Line Service Applications

Use the Dorman 904-484 when servicing fuel fittings that use a 5 mm disconnect interface. It is a practical choice for fuel line work on Chevrolet Colorado, Chevrolet Silverado 1500, Chevrolet Silverado 2500 HD, GMC Canyon, and GMC Sierra applications where a clean fuel line release is needed. This part cross-references Monroe Shocks & Struts (e.g., CH49736) for the same application.

What This Tool Helps Solve

• Stuck fuel line fittings that resist manual separation
• Reduced risk of bending or cracking fuel line connectors
• Longer repair times during fuel system service
• Difficulty accessing quick disconnect fuel fittings in tight spaces
• Need for a dedicated 5 mm fuel line disconnect tool

Installation Notes and Tips

Align the tool with the fuel fitting, press it into the connector, and release the line once the lock is disengaged. Confirm the fitting size before use, since this tool is specified for 5 mm connectors. It is not rated for transmission lines, hydraulic lines, or air conditioning lines.

Quality Assurance

Dorman designs service tools for straightforward repair work and reliable fitment on the applications listed. The 904-484 is intended for fuel line service on select Chevrolet and GMC vehicles, including Silverado, Sierra, Colorado, Canyon, Express, and Savana models.
