A-Premium Electric Fuel Pump Assembly for Nissan Titan/Armada VK56DE 5.6L V8 — Direct-Fit with Sending Unit

A-Premium Electric Fuel Pump Assembly is a replacement in-tank fuel pump kit designed to restore reliable fuel delivery for select Nissan and Infiniti V8 models (VK56DE) with an easy direct-fit installation.

This A-Premium assembly is engineered as a drop-in replacement for Nissan Titan, Armada and Infiniti QX56 models from the mid-2000s that use the VK56DE 5.6L V8 engine. It recreates the factory layout and connections—pump, sending unit, seal and strainer—so you get consistent fuel flow and accurate level readings without custom modifications. Backed by a one-year unlimited-mileage warranty, the kit targets owners who need a dependable, vehicle-specific repair part rather than a universal retrofit.

Which vehicles is this pump compatible with?

This assembly fits several specific Nissan and Infiniti models that use the VK56DE engine and matching fuel module pattern. Check model year cutoffs and reference numbers to confirm fit before ordering.

• Infiniti QX56 2004–2006 V8 5.6L (VK56DE)
• Nissan Armada 2005–2006 and certain 2004 models (up to 08/01/2006)
• Nissan Titan 2004–2007 V8 5.6L with the VK56DE engine (some 2006–2007 units limited to dates to 08/01/2006)
• Compare OEM reference numbers: 17040-7S000, 17040-7S00A, 17040-7S20A, 17040-ZQ60A and equivalent aftermarket codes

What components are included and why they matter?

The kit contains the core module parts you need to replace a failing in-tank pump and restore proper operation. Each component replicates the factory arrangement to preserve fit and function.

• Electric fuel pump — primary pressurization and flow source
• Fuel sending unit — maintains accurate fuel gauge readings
• Seal ring — prevents leaks at the tank flange
• Strainer (sock) — filters debris before fuel reaches the pump

How difficult is installation and what should a DIYer expect?

Installation is straightforward for someone with moderate mechanical skills and the right tools, especially since this is a direct-fit module. Expect a tank access procedure or partial fuel system disassembly depending on vehicle year and configuration.

• Requires basic tools and common shop safety—relieve fuel pressure first
• Drop-in design reduces modification and wiring changes
• Follow vehicle service manual for tank access and torque specs
• Professional installation recommended if you lack fuel-system experience

What quality assurances and part references should I check?

A-Premium supplies a one-year unlimited-mileage guarantee for this assembly, and the product lists multiple OEM reference numbers to help match your original part. Verify those codes against your vehicle’s original pump before purchase.

• One-year unlimited-mileage warranty from A-Premium
• Cross-reference numbers: 17040-7S000, 17040-7S00A, 17040-7S20A, 17040-ZQ60A and aftermarket codes
• Inspect connectors and flange orientation to confirm direct fit
• Compatible with A-Premium part group: pump, sending unit, seal, strainer

Who is this for: This A-Premium Electric Fuel Pump Assembly is aimed at owners and independent mechanics working on Nissan Titan, Armada or Infiniti QX56 SUVs and trucks from the 2004–2007 era that require a direct-fit replacement for the VK56DE 5.6L V8. It’s ideal for those who want a complete in-tank module that matches factory layout, reduces installation time, and comes with a warranty for peace of mind.
