E3950M Fuel Pump Module for Chevrolet, Oldsmobile, and Pontiac Cars

Extended cranking, intermittent no-start, low fuel pressure, hesitation under load, stalling, abnormal pump operation, or an inaccurate fuel-gauge reading can involve the in-tank module. This BDFHYK E3950M electric fuel pump module assembly is an aftermarket replacement for specific 1998–2000 Chevrolet, Oldsmobile, and Pontiac gasoline applications. The year range is not shared by every model, and Cavalier or Sunfire fitment requires the correct steel fuel tank. Confirm the exact vehicle, engine, tank material, sender arrangement, and OE number before installation.

Confirm E3950M Vehicle, Engine, and Tank Fitment

1999–2000 Chevrolet Cavalier with the 2.2L or 2.4L L4 engine and the applicable steel fuel tank
1998–1999 Chevrolet Malibu with the 2.4L L4 or 3.1L V6 engine
1999 Oldsmobile Alero with the 2.4L L4 or 3.4L V6 engine
1998–1999 Oldsmobile Cutlass with the 3.1L V6 engine
1999 Pontiac Grand Am with the 2.4L L4 or 3.4L V6 engine
1999–2000 Pontiac Sunfire with the 2.2L or 2.4L L4 engine and the applicable steel fuel tank

Do not use the broad 1998–2000 range for every model. Plastic-tank and steel-tank applications can require different module geometry.

E3950M OE and Interchange Number Check

Listed references include E3950M, FG0115, P74781M, SP6181M, MU1780, MU181, 19179627, 25317984, 25322178, F2961A, 530-2360, 67472, 953-0015, and A43005.

Comparable FG0115 configurations include the fuel-level sender, strainer, seal, wiring harness, and fuel-tank pressure sensor, while the lock ring is not normally included. Compare the tank opening, connector, line fittings, module depth, sender, float arm, pressure sensor, seal, and retaining arrangement.

Check the Fuel System Before Replacing E3950M

Measure fuel pressure during key-on, cranking, idle, and load
Check voltage and ground at the module under pump load
Inspect the relay, fuse, wiring, connector, filter, lines, regulator, and injectors
Test the sender, gauge circuit, and tank-pressure circuit separately where applicable

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

E3950M Installation Notes

Relieve fuel pressure, disconnect the battery, identify the tank material, support and clean the tank, and compare the old and new modules. Use the correct seal and verify retaining-ring engagement. After installation, prime the system, confirm pressure, inspect for leaks, verify gauge operation, and recheck the electrical and pressure-sensor circuits.

Before Ordering the E3950M Fuel Pump Assembly

Confirm the exact model-specific year and engine listed above
For Cavalier and Sunfire, verify the steel fuel tank or without-plastic-tank requirement
Match E3950M or the applicable OE/interchange number
Compare the connector, lines, pressure sensor, module height, sender, and float arm
Confirm the seal, retaining hardware, and package contents shown with the product

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

What’s Included in This Fuel Pump Assembly

Complete fuel pump module
Integrated fuel level sending unit
Fuel strainer (filter sock)
Housing and mounting components

This fuel pump assembly is designed as a direct replacement unit that restores proper fuel delivery and fuel level monitoring.

Estimated Installation Time

Professional mechanic: 1–2 hours
DIY installation: 2–4 hours

Fuel pump replacement usually requires accessing the fuel tank or service panel depending on the vehicle design. Always disconnect the battery and relieve fuel system pressure before installation.

Pump Only vs Fuel Pump Assembly

Option	Description
Replace Pump Only	Lower parts cost but requires disassembling the existing module and reusing older components.
Replace Complete Assembly	A complete module designed for direct installation, helping restore reliable fuel delivery more efficiently.

Most modern vehicles use integrated fuel pump modules, which makes replacing the full assembly the more reliable solution.

Q: Does E3950M fit every 1998–2000 Cavalier, Malibu, Sunfire, Alero, Cutlass, or Grand Am?

A: No. Each model has a specific year and engine range, and Cavalier or Sunfire fitment also depends on the fuel-tank material.

Q: Which Chevrolet Cavalier applications are listed?

A: The listed range is 1999–2000 Cavalier with the 2.2L or 2.4L L4 engine and the applicable steel fuel tank.

Q: Which Chevrolet Malibu applications are listed?

A: The listed range is 1998–1999 Malibu with the 2.4L L4 or 3.1L V6 engine.

Q: Which Alero, Cutlass, and Grand Am applications are listed?

A: Listed applications include 1999 Alero 2.4L/3.4L, 1998–1999 Cutlass 3.1L, and 1999 Grand Am 2.4L/3.4L.

Q: Why must the steel fuel tank be checked?

A: Steel and plastic tanks can use different openings, module depths, sender geometry, and retaining arrangements.

Q: Can E3950M replace FG0115 or P74781M?

A: Those numbers are listed as cross-references, but the tank material, connector, fittings, module height, pressure sensor, sender, and float arm must also match.

Q: Is a fuel-tank pressure sensor included?

A: Comparable FG0115 configurations include a pressure sensor. Confirm the supplied module and sensor connector before installation.

Q: Will E3950M correct a no-start condition?

A: Only when testing confirms low pressure, insufficient pump output, or an internal module fault. Other electrical, ignition, injector, air, or control faults can cause similar symptoms.

Q: What should be inspected inside the tank?

A: Inspect for rust, sediment, water, degraded fuel, debris, damaged baffles, and pickup restrictions before installation.

Q: What should be checked after installation?

A: Prime the system, verify pressure, inspect for leaks, confirm gauge operation, and recheck the electrical and tank-pressure circuits where applicable.
