Detailed Description

Sparta PN2039 is an OE-style electric fuel pump for in-tank installation on gas-powered vehicles. It is engineered for specific applications and is listed for 1989-1991 Nissan Maxima, 1993-1994 Nissan Maxima, and 1997-2001 INFINITI Q45. This part number, PN2039, is a practical replacement choice when servicing a fuel delivery system that needs consistent pressure and flow from an internal turbine pump.

This part cross-references Airtex E8190 and Spectra Premium SP1139 for the same application. Use PN2039 when replacing a worn in-tank pump on a Nissan Maxima or INFINITI Q45 and you need a direct-fit fuel pump assembly component with the correct electrical and outlet configuration.

Common Problems It Can Address

• Hard starting caused by weak fuel pressure
• Engine hesitation from inconsistent fuel delivery
• Stalling related to a failing in-tank pump
• Loss of power under load from low fuel flow
• No-start conditions tied to pump wear in the fuel tank

Installation Notes and Tips

Install PN2039 in the tank position only and verify the vehicle uses the listed specific-fit application before service. Confirm connector shape, terminal style, inlet and outlet configuration, and pressure requirements against the original unit before installation. Replace any worn fuel system components during service and follow the included instruction sheet for wiring and hose connection details.
