Gledewen Fuel Pump Driver Module (FPDM) 590-001 - 2004–2011 Ford/Lincoln/Mazda/Mercury, upgraded microprocessor & mounting kit

Gledewen 590-001 is a direct-replacement fuel pump driver module engineered to restore proper fuel-pump control and reduce electrical failures in compatible 2004–2011 Ford, Lincoln, Mazda and Mercury models.

This fuel pump driver module (FPDM) is a plug-and-play replacement built with an upgraded microprocessor and corrosion-resistant finishes to improve response and longevity. It comes with mounting bolts and rubber bushings to simplify installation and isolate the module from chassis vibration and moisture. The assembly replaces several OE part numbers including 4C2A-9D372-BA, 5L8A-9D370-AA and ZZC0-18-940, and fits a wide range of V6, V8 and select V10 applications.

How does this module solve fuel delivery and stalling issues?

The module manages the signal and current that the vehicle’s electrical system sends to the in-tank fuel pump. Gledewen’s re-engineered microprocessor improves reaction time and reduces the chance of intermittent electrical faults that lead to loss of fuel pressure or sudden shutdowns. Replacing a failing FPDM often returns stable pump operation without replacing the pump itself.

• Upgraded microprocessor for faster response to ECU commands
• Restores stable fuel pressure by correcting pump control signals
• Plug-and-play wiring harness matches factory connectors for easier swap

What are the durability and corrosion protections included?

This unit is powder-coated and supplied with rubber mounting bushings to reduce metal-to-metal contact and block moisture ingress around the housing. Those design choices limit galvanic corrosion and vibration stress that can prematurely damage driver modules mounted directly to the frame. The included mounting hardware positions the module slightly apart from the chassis to further reduce exposure.

• Powder-coated housing to resist rust and road salts
• Rubber bushings to absorb vibration and prevent abrasion
• Mounting bolts included for correct spacing and secure fitment

Which vehicles and OE numbers does this replace?

The Gledewen 590-001 fits many 2004–2011 Ford, Lincoln, Mercury and Mazda models, covering multiple engine options from 2.3L four-cylinder to 6.8L V10. It is a factory-style replacement for numerous OE part numbers, so you can match by the listed codes to confirm fit. Refer to the vehicle list and OE cross-reference when ordering to ensure compatibility.

• Fits: Ford Crown Victoria, F-150, F-250/350 Super Duty, Mustang, Escape, Expedition, Explorer Sport Trac and more
• Also fits: Lincoln Navigator, Mark LT, Town Car; Mercury Mariner, Grand Marquis; Mazda Tribute
• Replaces OE numbers including 4C2A-9D372-BA, 5L8A-9D370-AA, ZZC0-18-940 and related variants

Who is this for? Installers, DIY mechanics and fleet technicians who need a reliable FPDM replacement for mid-2000s to early-2010s Ford-family vehicles. Choose this module when diagnosing intermittent pump operation, no-starts linked to pump control, or when the original driver module shows signs of heat- or corrosion-related failure. Backed by a 12-month warranty and designed for straightforward installation, it provides a cost-effective alternative to replacing the entire fuel-pump assembly in many cases.
