FEIDKS E3581M Electric Fuel Pump Module Assembly - Direct Fit

In this review the FEIDKS E3581M Electric Fuel Pump Module Assembly is evaluated as a direct replacement for mid-2000s GM full-size SUVs. The bottom line: this module is aimed at DIY mechanics and independent shops who need a full, ready-to-install fuel module that includes the pump, level sensor, seal and small plastic parts to restore fuel delivery quickly. It stands out for ease of installation, OE-style fitment, and value compared with dealer pricing, though buyers should be aware of mixed long-term reliability reports.

Key Features

• Complete module: Ships as a single assembly with pump, new fuel level sensor and floater arm so the repair replaces all wear items at once.
• OE fit: Built to match original equipment dimensions and listed OEM part numbers for a direct fit on compatible 2004-2007 models.
• Durable materials: Constructed from materials that meet OE standard to resist typical fuel system exposure and provide secure operation when installed correctly.
• Noise and comfort: Designed to run with low noise to avoid adding cabin buzz or vibration after replacement.
• Installation kit included: Comes with a new tank seal/O-ring, two plastic parts and quick instructions so the job requires fewer trips to the parts store.

Who It's For

This module is best for owners of 2004-2007 Tahoe, 2004-2006 and 2007 Escalade, and 2004-2007 GMC Yukon models who want a full replacement instead of swapping individual components. It suits knowledgeable DIYers comfortable dropping the fuel tank or working with fuel system components and independent repair shops seeking lower-cost alternatives to dealer modules.

Those who prioritize guaranteed long-term warranty coverage from a dealer or who need parts for other vehicle years or makes should look elsewhere. Buyers who are not comfortable with fuel system work should use a professional installer to avoid safety risks.

Pros & Cons

Pros

• Easy to install for experienced hands and includes all small parts needed for a single-job replacement.
• Fits the listed models closely thanks to matching OEM part numbers and form factor.
• Good value compared with dealer pricing when replacing the entire module yourself.
• Quiet operation reduces added cabin noise after installation.

Cons

• Some customers reported early failures within weeks, so long-term durability may be variable for certain units.
• Fuel gauge readability issues have been reported by a minority, indicating the level sensor may not always match original calibration.
