The Dorman 904-517 Diesel Fuel Filter Housing is a direct-replacement housing designed to stop fuel leaks from a damaged coupling and restore reliable fuel delivery to compatible Chevrolet and GMC 2500/3500 trucks.

If your truck shows signs of fuel leakage around the filter area, or you’ve experienced rough-start or no-start symptoms tied to a compromised filter coupling, this replacement housing provides a straightforward repair without the need for modifications. Built to match original-fit dimensions and supplied with the installation hardware, the assembly is intended to make the swap fast and minimize downtime.

How does this housing stop fuel leaks and related starting problems?

Leaking at the filter housing coupling lets air into the fuel system or allows fuel to escape, causing hard starts and engine hesitation. Replacing the faulty housing restores a sealed connection and keeps fuel pressure stable through the filter assembly.

• Replaces the damaged coupling that commonly causes leaks
• Restores correct sealing surfaces and fuel routing
• Helps prevent air intrusion that leads to rough or no-start conditions
