Dorman Fuel Pump Driver Module replacement 590-001 — powder-coated housing, raised mount, includes mounting bolts

Dorman 590-001 is an OE FIX replacement fuel pump driver module engineered with a powder-coated housing, vibration-isolating bushings, and an upgraded microprocessor to restore reliable fuel pump control on compatible Ford, Lincoln, Mazda, and Mercury vehicles.

Many OEM fuel pump driver modules degrade over time because they sit against the vehicle frame where road salt, moisture and debris accelerate corrosion and electrical failure. Dorman rethought the assembly: the 590-001 moves the module away from direct frame contact, uses a more durable exterior finish and installs a reengineered control microprocessor. It ships with new mounting hardware for a straightforward replacement and is built and tested in the United States.

How does this replacement reduce corrosion and extend service life?

The 590-001 tackles the root causes of premature failure by changing how the module mounts and by improving the housing material. Rubber bushings lift the module off the steel frame to limit galvanic contact and debris accumulation, while the powder-coated die-cast housing resists environmental wear better than many original parts.

• Powder-coated housing for improved environmental resistance
• New rubber bushings isolate module from frame contact
• Raised mounting position reduces road-debris buildup underneath
• Includes two sets of fresh mounting fasteners for secure installation

What improvements does the internal electronics offer?

Dorman upgraded the internal microprocessor to improve response and control of the fuel pump. The updated electronics are designed to match OE functionality while offering enhanced tolerance to real-world operating conditions, lowering the chance of intermittent faults.

• Reengineered microprocessor for faster response times
• Assembly and final testing performed at Dorman’s Pennsylvania facility
• Engineered to meet expected OEM electrical behavior

Will this module fit my vehicle and what does installation include?

Fitment varies across model years and configurations; always confirm compatibility using the product’s garage tool and the Confirmed Fit information shown on the product page. Dorman includes two sets of new mounting bolts so you have the hardware needed for a complete replacement.

• Check the Confirmed Fit bar and any "i" icons for vehicle-specific notes
• Includes two sets of mounting fasteners for a full installation
• Designed to be a direct replacement for listed Ford, Lincoln, Mazda and Mercury models

How does choosing an OE FIX part benefit me over cheaper knock-offs?

OE FIX parts are engineered to correct known failure modes of the original component rather than merely copying the original design. Dorman’s improvements address corrosion, mounting problems and electronic responsiveness, lowering the likelihood of repeat failures compared with lower-cost replicas that don’t incorporate these fixes.

• Specifically redesigned to avoid common OEM failure points
• U.S. engineering and controlled assembly/testing processes
• Backed by Dorman’s quality controls for consistent performance

Who is this for: The Dorman 590-001 Fuel Pump Driver Module is intended for owners and technicians servicing compatible Ford, Lincoln, Mazda and Mercury vehicles where the original module has corroded, failed, or shows intermittent electrical faults. It’s a practical upgrade for anyone seeking a longer-lasting replacement with easy fit verification and complete mounting hardware supplied.
