GM GENUINE PARTS Fuel Pump Control Module 13565641 — OE Fit for Chevrolet Buick GMC Cadillac, Factory-Tested

GM Genuine Parts 13565641 is a factory-backed fuel pump control module that manages power delivery to your vehicle's fuel pump for reliable operation.

Designed and validated by GM engineers, the 13565641 Fuel Pump Control Module replaces the original unit installed in compatible Chevrolet, Buick, GMC, and Cadillac models. This module routes electrical power to the fuel pump based on the vehicle's control signals and system demands. It’s manufactured to the same design intent and testing standards used in production, and may previously have been listed under ACDelco GM Original Equipment (OE).

How does this module affect fuel system performance?

The control module regulates the electrical feed to the fuel pump so the pump runs when the engine needs fuel and reduces strain when it doesn’t. Proper operation helps maintain consistent fuel pressure and reduces unnecessary pump wear. It does not alter engine tuning, but it supports the fuel delivery system's stability.

• Ensures correct power sequencing for the fuel pump during start and run cycles
• Minimizes electrical stress on the pump through controlled activation
• Contributes to stable fuel pressure under varying engine loads

Will this part fit my GM vehicle?

Compatibility depends on your vehicle’s year, make, model, and original equipment part number. GM Genuine Parts are engineered to match OE specifications for specific GM vehicles, so replacing the original module with part 13565641 maintains factory fit and function. Always verify fitment using your VIN or parts catalog before purchase.

• Designed for select Chevrolet, Buick, GMC, and Cadillac applications
• Cross-reference with OEM part number 13565641 for exact matches
• Use VIN-based lookup or dealer parts guide to confirm compatibility

What should I expect during installation and maintenance?

Installation typically requires access to the fuel pump module location and a few electrical connections; procedures vary by model. Technicians often remove battery power first, disconnect connectors, and secure the replacement module in the original mounting points. Routine maintenance involves checking connectors and harnesses for corrosion or damage rather than frequent module service.

• Disconnect battery before handling electrical components
• Inspect wiring harness and terminals for corrosion or loose pins
• Securely mount the module in the original location using factory fasteners

How does choosing a GM Genuine Parts module benefit me?

Choosing a GM Genuine Parts module means you get a component engineered to the same standards the vehicle was built with, plus validation by General Motors. That alignment with factory engineering reduces fitment surprises and ensures the module integrates with the vehicle’s existing systems. Some customers find that OE-backed parts simplify diagnostics and future service at dealerships.

• Factory engineering and validation for GM vehicles
• Designed to meet production testing and performance criteria
• Often accepted by dealerships for warranty and service continuity

Who is this for: Drivers and technicians seeking a direct OE-replacement fuel pump control module for compatible Chevrolet, Buick, GMC, or Cadillac vehicles. Ideal for owners who prefer factory-specified components to preserve original equipment fit and electrical behavior, and for repair shops that require parts validated by General Motors.
