Electric Fuel Pump Assembly E8545M Compatible with 04-09 Nissan

In this review of the Electric Fuel Pump Assembly E8545M, the bottom line is straightforward: this is a practical, budget-conscious replacement for Nissan owners who need a working in-tank fuel pump. It is aimed at DIY mechanics and independent shops replacing pumps on 2004-2009 Nissan Altima, Maxima and Quest models. The biggest reason to buy is value for money combined with a tested, high performance pump core designed to restore fuel delivery without the premium cost of an OE unit.

Key Features

• Premium materials: Built using all new components under quality-controlled manufacturing to deliver long life and reliable operation.
• High performance core: The pump core is selected for stable oil and fuel supply which helps maintain steady engine performance under load.
• Wide compatibility: Direct fit for 2004-2006 Nissan Altima L4 2.5L and V6 3.5L, 2004-2008 Maxima V6 3.5L and 2004-2009 Quest V6 3.5L to simplify purchasing for those models.
• Interchange numbers provided: Replaces common part numbers such as F4556A, E8545M and several OEM references to aid cross-referencing during replacement.
• Tested for performance: Manufactured and inspected under controlled procedures so it arrives ready to restore fuel system function for most routine failures.

Who It's For

This pump is best for owners of compatible Nissan Altima, Maxima or Quest vehicles who are comfortable doing an in-tank fuel pump swap or who work with an independent mechanic. It fits both 2.5L L4 and 3.5L V6 applications listed, making it a convenient single-source replacement when the original pump fails.

It is less suitable for buyers who demand OEM-branded parts from the vehicle maker or those who want extended warranty coverage from a dealer. Also, if your vehicle has atypical modifications or a nonstandard fuel system, confirm fitment carefully before purchase.
