Fuel Pump Module Assembly for OE-Style Fuel Delivery

Hitachi FUP3303 is a fuel pump module assembly built for vehicles that need consistent fuel pressure and volume for reliable engine operation. It serves a wide range of applications, including Ford Explorer, Mazda 626, and Mitsubishi Montero Sport models across multiple years.

Engineered with precision-machined internal components, this fuel pump module assembly is designed to reduce internal friction and support efficient operation. The result is a fuel delivery component focused on durability and steady performance in everyday driving conditions.

Key Features

• Fuel pump module assembly for air and fuel delivery systems
• Precision-machined internal components for efficient pump operation
• Built to deliver the fuel pressure and volume required by modern engines
• Reduced internal friction for improved operating efficiency
• Hitachi FUP3303 application coverage across multiple Ford, Mazda, Mitsubishi, Isuzu, Acura, Honda, Lincoln, and Mercury models

Detailed Description

Hitachi FUP3303 is a replacement fuel pump module assembly for a broad range of vehicles, including 1995-2000 Ford Explorer, 1995-2002 Mazda 626, and 2001-2004 Mitsubishi Montero Sport applications. It is also listed for select Ford F-Series, Econoline, Expedition, Ranger, and Lincoln Navigator models, along with several Acura, Honda, Mercury, and Isuzu applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

As a fuel delivery component, the module supports the pressure and volume needed for proper combustion, throttle response, and stable engine operation. The Hitachi FUP3303 part number is also referenced in supersession listings as FUP3303-D for many of the covered vehicles.

What It Helps Address

• Hard starting caused by weak fuel delivery
• Engine hesitation from inconsistent fuel pressure
• Loss of power under load due to inadequate fuel volume
• Rough running related to a failing pump module
• Fuel delivery issues on high-mileage Ford Explorer, Mazda 626, and Mitsubishi Montero Sport vehicles

Installation Notes and Tips

Verify the vehicle year, make, model, and notes before ordering. Fitment includes specific date-based coverage such as 2000 Mitsubishi Montero Sport from 01/06/2000 and 1998 Mazda B2500 and B4000 to 08/17/1998. Confirm the existing fuel system configuration and compare the original part number, especially where supersession to FUP3303-D is listed. Professional installation is recommended for fuel system service.

Quality Assurance

Hitachi fuel pumps are built with internal precision machining to support efficient operation and longer service life by reducing friction. That construction focus helps provide dependable fuel pressure and volume for the listed applications.
