Key Features

• Electric 12V pump with a 13 flow rating and 109.0 minimum pressure.
• Fuel sending unit included for integrated fuel level reporting.
• In-tank, internal design with quick-connect outlet and port inlet.
• Plastic housing with a trapezoid male connector and blade terminals.
• Strainer and gasket included for a more complete fuel system service.
• Airtex E8797M is built for specific-fit applications, not universal use.

Detailed Description

Airtex E8797M is engineered as a fuel pump module assembly for direct replacement in select Lexus GX470 and Toyota 4Runner models. The module uses a 4-wire electrical layout, 20-gauge wiring, and a 300.0 wiring harness length, with a grey connector and male terminals for the specified application. Its fuel sensor design is intended to resist corrosive fuel blends and additives, while the in-tank configuration supports the original fuel system layout.

Airtex positions this fuel system line around premium fit, form, and function, with OE-level reliability targets across its pump modules, hanger assemblies, tank reservoirs, and sender assemblies. The E8797M part number is also referenced by Delphi FG1761 and cross-references 77020-35100 and 77020-35101 for the same application.

Common Replacement Uses

• Restoring fuel delivery when the pump no longer maintains pressure.
• Addressing inaccurate fuel level readings from a worn sending unit.
• Correcting hard-start or no-start conditions tied to fuel supply loss.
• Replacing a noisy or inconsistent in-tank fuel pump assembly.
• Servicing a leaking or degraded module seal area during fuel system repair.

Installation Notes

Verify the vehicle build date before ordering, since 2005 applications are listed from 11/01/2004. Confirm connector shape, outlet style, and top mount diameter against the original module before installation. Mounting hardware is not included. The E8797M is a specific-fit in-tank assembly, so matching the application details is important for proper installation.

Quality Assurance

Airtex states that this fuel pump module is built to meet or exceed OEM fit and reliability standards. The brand also notes that many applications include problem-solving features such as patented high-gradient density strainers and wiring harnesses, along with fuel sensor materials chosen for resistance to corrosive fuel blends and additives.
