Detailed Fitment and Function
Compatible with 2004-2009 Nissan Quest, 2004-2008 Nissan Maxima, and 2004-2006 Nissan Altima applications listed in the fitment data, this module is built for vehicles that use an in-tank fuel delivery setup. The E8545M is a practical replacement when the original module has worn pump components, inaccurate fuel level reporting, or sealing issues at the tank opening. This part cross-references Bosch 67991 and Delphi FG0987 for the same application.
Airtex fuel system components are developed around premium fit, form, and function, with coverage focused on OE-style service replacement needs. The E8545M part number appears in Airtex fuel pump module listings and should be matched to the exact vehicle notes, including the 2004 Altima build-date and California emissions exclusions shown in the fitment table.
Common Service Issues
- Hard starting caused by weak fuel delivery

- Loss of pressure from pump wear or internal leakage
- Tank sealing problems related to a damaged gasket or seal
- Fuel starvation from a restricted or worn strainer
Installation Notes
Verify the vehicle build date and emissions notes before ordering, especially for 2004 and 2005-2006 Altima applications. Confirm the connector style, outlet connection, and tank configuration against the original module before installation.
