XYgdhqpt EBP Tube Fitting 3C3Z-9F485-BA — Direct-Replace Metal Exhaust Back Pressure Tube for 6.0L/6.4L/7.3L Powerstroke

XYgdhqpt 3C3Z-9F485-BA is a direct-replacement exhaust back pressure (EBP) tube fitting designed to restore correct exhaust back pressure routing on Ford Powerstroke diesel engines from the late 1980s through 2010.

If your diesel’s exhaust back pressure system has a leaking, corroded, or missing tube fitting, this XYgdhqpt part offers a durable metal replacement built to withstand high heat and corrosive exhaust environments. It’s engineered to match factory thread and fit specifications so you can reinstall the EBP tube and return the exhaust system to proper operation without modifying the manifold or sensor plumbing.

Will this EBP tube fitting fit my Ford Powerstroke engine?

Yes—this XYgdhqpt 3C3Z-9F485-BA is listed for multiple Powerstroke engines and compatible Ford trucks across model years. Check your vehicle’s engine size and year against the compatibility list to confirm fit before ordering.

• Compatible engines: 6.0L, 6.4L, 7.3L Powerstroke diesels.
• Common fitments: 1988–1996 F-250, 1988–1997 F-350, 2000–2008 F-650/F-750, and 1994–2010 Powerstroke applications.
• OEM part number reference: 3C3Z-9F485-BA for cross-checking with build sheets.

How durable is the replacement fitting for high-heat exhaust conditions?

The XYgdhqpt fitting is fabricated from high-quality metal selected for heat and corrosion resistance, so it tolerates the thermal cycles and exhaust byproducts common to diesel operation. Proper installation and thread preparation further extend its service life under heavy-duty conditions.

• Material resists oxidation and exhaust corrosives.
• Designed for stable performance under sustained heat exposure.
• Recommended anti-seize on threads to prevent galling and aid future removal.

What should I know about installation and maintenance?

Installing the EBP tube fitting is straightforward for anyone comfortable with basic exhaust or manifold work; however, attention to thread condition and sealing technique matters for a leak-free repair. If threads are damaged, chasing with the correct 1/4 NPT tap is advised before installing the new fitting.

• Package contains one XYgdhqpt EBP tube fitting (3C3Z-9F485-BA).
• Lightly coat threads with high-temperature anti-seize compound before assembly.
• If old threads are damaged, chase exhaust manifold threads with a 1/4 NPT tap for best results.

Can replacing this fitting affect engine performance or diagnostics?

Replacing a damaged or leaking EBP tube fitting helps maintain the exhaust back pressure routing that many engine control and turbo systems rely on, potentially stabilizing sensor readings and turbo behavior. While the fitting itself is a mechanical part, restoring proper connections supports accurate system operation.

• Replaces worn or corroded original fitting to stop exhaust leaks.
• Helps preserve correct back pressure routing to sensors and plumbing.
• Supports consistent turbo and exhaust system performance when installed properly.

Who this is for: technicians, diesel owners, and fleet managers who need a reliable, OEM-referenced EBP tube fitting for older and newer Ford Powerstroke diesel trucks. If you’re repairing exhaust leaks, refreshing manifold fittings during a rebuild, or maintaining a work truck fleet, this XYgdhqpt 3C3Z-9F485-BA offers a durable replacement that matches factory specifications and helps keep exhaust systems functioning as intended.
