E3609M Electric Fuel Pump Assembly with Pressure Sensor - Direct Fit

In this review of the E3609M electric fuel pump assembly, the bottom line is simple: this is a practical, cost-conscious replacement for owners of 2004-2006 Chevy Silverado and GMC Sierra 1500/2500 HD models with a 78 in short bed who need a direct OE-style swap. The reviewer found the unit useful for restoring fuel delivery and for customers who value ease of installation, since the assembly arrives with a pre-installed pressure sensor, level sender and factory-style connectors so no tank modifications are required.

Key Features

• Direct OE fit: Designed to match factory dimensions so it installs without modification on 78 in bed Silverado and Sierra models, saving time during replacement.
• Built-in pressure sensor: The integrated pressure sensor helps maintain correct fuel pressure for reliable cold starts and steady operation under load.
• Complete assembly: Includes level sender, wiring harness and sealing ring so a single part replaces the entire in-tank module rather than requiring extra components.
• Multiple connectors: Comes with 2-pin and 4-pin plugs plus three tube ports to match original wiring and fuel line arrangements on compatible trucks.
• Corrosion-resistant housing: Precision-molded plastic construction resists fuel degradation and corrosion, which helps longevity in a used fuel environment.

Who It's For

The E3609M assembly is aimed at owners and independent mechanics working on 2004-2006 Chevrolet Silverado and GMC Sierra 1500/2500 HD trucks with a 78 in short bed, including 2007 Classic trims, who need a direct replacement that restores fuel delivery and maintains factory-style gauge and harness connections. It is especially useful when the original pump or sender has failed and a like-for-like swap is preferred.

Drivers with different bed lengths, diesel engines, or newer model years should look elsewhere; this unit is explicitly designed for gas engines in specified years and bed length and will not fit vehicles outside those parameters.

Pros & Cons

Pros

• Direct OE replacement with pre-installed pressure sensor and sender for straightforward installation.
• Matches factory flow and pressure characteristics to support reliable starts and smooth driving.
