Spectra EM1504DSP Diesel Exhaust Fluid (DEF) Pump

Spectra EM1504DSP DEF Pump Overview

The Spectra EM1504DSP diesel exhaust fluid pump transfers DEF from the tank to the injector through the heater injector hose while meeting OE pressure and flow rate requirements. It is a direct-fit emission control component for diesel applications that need stable DEF delivery and consistent system operation.

Compatible With 2011-2016 Ford F-250 Super Duty, 2011-2016 Ford F-350 Super Duty, 2015-2019 Ford Transit-150, 2015-2019 Ford Transit-250, 2015-2019 Ford Transit-350, and 2015-2019 Ford Transit-350 HD. The Spectra EM1504DSP is validated by in-house Canadian engineering review to meet OE requirements.

Key Features

• Diesel exhaust fluid pump for emission control system service
• Transfers DEF from the tank to the injector through the heater injector hose
• Built to meet or exceed OE pressure and flow rate specifications
• Tank-mounted design for the listed Ford diesel applications
• Validated by Spectra Premium’s in-house Canadian engineering team

Detailed Description

The Spectra EM1504DSP is a replacement DEF pump for Ford diesel trucks and vans that rely on accurate fluid delivery for emission system performance. It supports DEF movement from the tank to the injector, helping maintain the pressure and flow characteristics required by the vehicle’s emission control system. This part number, EM1504DSP, is a practical OE-style solution for service work on Ford F-250 Super Duty, Ford F-350 Super Duty, and Transit diesel models.

This part cross-references Standard Ignition DFIP1 for the same application.

What It Helps Address

• DEF delivery faults caused by a weak or failing pump
• Low pressure or inconsistent flow in the DEF supply circuit
• Emission system warnings related to DEF transfer performance
• Poor injector feed from the tank-to-injector supply path
• Service replacement needs on Ford diesel emission components

Installation Notes and Tips

Install the pump on the tank as specified for the application. Verify the vehicle year, model, and emission system configuration before installation, and inspect the heater injector hose and related DEF lines for contamination, leaks, or damage that could affect pump performance. Confirm all connections are secure and the system is properly primed after service.

Quality Assurance

Spectra Premium validates this DEF pump through in-house Canadian engineering review to help ensure OE requirement compliance for pressure and flow performance. Part number EM1504DSP is engineered for the listed Ford applications and emission control service needs.
