Installation Note	Clean the tank, replace the seal and protect float-arm travel
Diagnostic Note	Test voltage, ground, relay, wiring and pressure before replacement

Hard starting, low measured fuel pressure, hesitation under load, intermittent stalling, or an inaccurate fuel gauge can point to an in-tank module fault after the power supply, ground, relay, wiring, and fuel lines have been tested. This E8788M replacement module is intended for specified 5.6L Infiniti QX56, Nissan Armada, and Nissan Titan applications. Confirm the original module number, model year, tank flange, electrical connector, fuel outlet, module height, and float-arm layout before ordering.

E8788M Application and Vehicle Coverage

This in-tank fuel pump module is organized for specified 2007–2010 Infiniti QX56 5.6L vehicles and 2007–2015 Nissan Armada and Titan 5.6L vehicles. Similar-looking modules can differ by model year, fuel-tank design, sender calibration, connector keying, and outlet orientation.

Fitment Verification

Match E8788M and the verified interchange number to the removed module.
Confirm 5.6L V8 application, exact model year, drivetrain, and fuel-tank configuration.
Compare the top flange, fuel-port count and orientation, connector shape, module height, and float-arm direction.
Do not substitute a module with a different sender range, pressure-sensor provision, or reservoir design.

Module Functions and Included Components

Electric in-tank pump supplies fuel to the engine-side delivery system.
Integrated reservoir and inlet strainer support pickup during normal vehicle movement.
Fuel-level sender and float arm report tank level to the instrument cluster.
Fuel-port arrangement and vehicle-specific electrical connection must match the original assembly.

Symptoms and Diagnostic Checks

Before replacing the module, measure fuel pressure and test voltage and ground at the connector under load. Inspect the relay, fuse, wiring terminals, fuel lines, evaporative-system connections, and tank for contamination. A restricted line, weak electrical feed, damaged connector, inaccurate sender circuit, or engine-management fault can produce similar symptoms.

Installation Notes

Relieve fuel-system pressure and disconnect the battery before opening the tank. Clean the tank and flange area, install a new compatible seal, position the float arm without bending it, and lock the module evenly. Prime the system before starting, inspect the flange and outlet for leaks, verify measured fuel pressure, and confirm normal fuel-gauge operation.

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: Which vehicles use the E8788M module?

A: It is intended for specified 2007–2010 Infiniti QX56 and 2007–2015 Nissan Armada and Titan vehicles with the 5.6L V8.

Q: Can fitment be confirmed by the 5.6L engine alone?

A: No. Model year, tank configuration, OE number, flange, connector, outlet, module height, and float-arm layout must also match.

Q: Is the fuel-level sender included?

A: Yes. The module includes a sender and float arm, but the calibration and arm geometry must match the original assembly.

Q: What fuel-port details should be checked?

A: Compare the number of ports, diameter, orientation, and quick-connect style directly with the removed module.

Q: Is the fuel tank pressure sensor included?

A: Sensor provision can vary among interchanges. Compare the original module and the product images before installation.

Q: What symptoms can indicate a module fault?

A: Low measured pressure, extended cranking, hesitation, stalling, and inaccurate gauge readings can indicate a fault after electrical and line checks.

Q: What should be tested before replacement?

A: Test pump voltage and ground under load, relay operation, connector condition, fuel pressure, line restriction, and the sender circuit.

Q: Why should the tank be cleaned?

A: Dirt, corrosion, or degraded fuel can damage the new pump and restrict the inlet strainer.

Q: Should the old tank seal be reused?

A: No. Install a new compatible seal and clean the sealing surface before locking the module into place.

Q: What checks are required after installation?

A: Prime the system, inspect for leaks, measure pressure, start the engine, and confirm that the gauge responds normally.
