E3591M Electric Fuel Pump Module Assembly For 2005-2008 Chevrolet Malibu/Pontiac G6/Saturn Aura 3.5L V6/2.4L L4/3.6L

E3591M Fuel Pump Module for Chevrolet Malibu, Pontiac G6, and Saturn Aura

Extended cranking, intermittent no-start, low fuel pressure, hesitation under load, stalling, or an inaccurate fuel-gauge reading can involve the in-tank module. This BDFHYK E3591M electric fuel pump module assembly is an aftermarket replacement for specific Chevrolet Malibu, Pontiac G6, and Saturn Aura applications. Fitment is not one shared 2005–2008 range: confirm the exact model year, engine, VIN, tank design, connector, module height, sender layout, and OE number.

E3591M OE and Interchange Number Check

Listed Cross-Reference Numbers

E3591M, FG1384, SP6602M, P76246M, 67521, M10153, M10119, 10376291, 19179818, 19169179, 22717995, 323-01738, 323-00508, and 323-00146.

Match the Number to the Physical Module

Compare the tank opening, flange, connector, line fittings, module depth, reservoir, pickup, strainer, sender, float arm, seal, and lock-ring engagement with the removed assembly. Model name alone is not enough because engine and production configurations differ.

Check the Fuel System Before Replacing E3591M

Fuel Pressure and Electrical Diagnosis

• Measure fuel pressure during key-on, cranking, idle, and load
• Check available voltage and ground at the module connector under pump load
• Inspect the relay, fuse, wiring, connector, fuel lines, pressure-control components, and injectors
• Test the sender and gauge circuit separately when the fuel-level reading is inaccurate

Inspect the Tank for Contamination

Rust, sediment, water, degraded fuel, or debris can restrict the strainer and damage the replacement pump. Clean the tank and correct the contamination source before installation.

Malibu, G6, and Aura Installation Notes

Record the VIN, Engine, and Original Module Number

Verify the vehicle application before removing the tank. Relieve fuel pressure, disconnect the battery, support the vehicle and tank correctly, and clean the tank opening before removal.

Prime, Leak-Test, and Confirm Gauge Operation

Compare the old and new modules, use the correct seal, and confirm full lock-ring engagement. After installation, prime the system, verify pressure, inspect the seal and fuel connections for leaks, confirm gauge operation, and recheck the electrical circuit.

Before Ordering the E3591M Fuel Pump Assembly

Model-Specific Fitment Checklist

• Confirm the exact Malibu, G6, or Aura model year and engine combination
• Do not use the combined product-title range as the only fitment check
• Do not infer 2.2L compatibility from the existing description
• Match E3591M or the applicable OE/interchange number
• Compare the tank opening, connector, line fittings, module height, sender, and float arm
• Confirm the seal, lock ring, and installation hardware shown with the product

This is a BDFHYK aftermarket replacement fuel pump module assembly, not a Chevrolet, Pontiac, Saturn, or GM factory OEM component.
