Spectra EM1508DFHS Diesel Exhaust Fluid (DEF) Hose

Spectra EM1508DFHS DEF Hose Overview

The Spectra EM1508DFHS is a heated diesel exhaust fluid hose for diesel emission control systems. It helps keep DEF moving from the pump to the injector during cold-weather operation, reducing the risk of freeze-related drivability issues and warning lights.

Compatible with 2011-2016 Ford F-250 Super Duty and 2011-2016 Ford F-350 Super Duty applications, this DEF hose is built to OE requirements and validated by Spectra Premium’s Canadian engineering team.

Key Features

• Heated DEF hose for diesel exhaust fluid transfer
• Helps prevent DEF freeze-up during normal vehicle operation
• Supports proper DEF delivery from pump to injector
• OE-requirement validation by in-house Canadian engineers
• Direct-fit application for Ford Super Duty diesel emission systems
• Part number: EM1508DFHS

Detailed Description

The Spectra EM1508DFHS diesel exhaust fluid hose is designed for emission control service on Ford Super Duty diesel trucks. By maintaining DEF flow in low temperatures, it helps preserve normal SCR system operation and reduces the chance of check engine light activation tied to frozen DEF transfer. This part cross-references Ford BC3Z5J249E and BC3Z5J249X for the same application.

What It Helps Address

• DEF freeze-up in cold weather
• Check engine light caused by DEF delivery interruption
• Reduced vehicle operating speed related to emission system faults
• Loss of DEF transfer from pump to injector
• Emission system service needs on Ford F-250 Super Duty and Ford F-350 Super Duty trucks

Installation Notes and Tips

Verify the vehicle’s year, model, and emission system configuration before ordering. Inspect the DEF lines, connectors, and surrounding components for damage or contamination during replacement. Confirm routing matches the original hose path on 2011-2016 Ford F-250 Super Duty and 2011-2016 Ford F-350 Super Duty applications.

Quality Assurance

Spectra Premium validates injector hoses against OE requirements through its in-house Canadian engineering team to support proper fit and function.
