Which truck models and engines does this pump fit?

This KacuYelin E4123M module is built specifically for first-line fitment with select Silverado and Sierra half-ton trucks. Confirm fitment against your vehicle year, engine displacement, and OE part number before purchase.

• Chevrolet Silverado 1500: 2014–2018 — 4.3L V6, 5.3L V8, 6.2L V8.
• GMC Sierra 1500: 2014–2017 (4.3L V6), 2014–2018 (5.3L and 6.2L V8).
• Matches reference numbers: E4123M / 13513407 / 13582491 / SP6714M / FG1832.
• Use vehicle fitment lookups (seller or retailer tool) to verify exact application.

How does this pump improve fuel delivery and durability?

The assembly uses a motor core with a carbon commutator and a refined impeller shape to reduce internal wear and improve suction efficiency. A high-mesh internal filter and stable fuel-level signal help protect the engine from contaminants and keep your gauge reporting accurately.

• Carbon commutator reduces arc wear for longer motor life.
• Scoop-style impeller optimizes flow and minimizes operational noise.
• Built-in high-mesh filter screens out particulate contaminants.
• Stable fuel-level output supports consistent dashboard readings.

What should I know before installing this replacement module?

Installation requires care: some modules are shipped without an inline fuel filter or with the fuel-level sensor detached. Clean the tank, confirm the sensor is seated properly, and consider replacing the external fuel filter at the same time to avoid introducing debris to the new pump.

• Check if your purchased unit includes the external fuel filter; replace filter if not included.
• Ensure fuel-level sensor locks securely into the module to prevent gauge errors.
• Drain and inspect the tank for sludge or large debris before fitting the new module.
• Regularly inspect the module screen and replace if heavy blockage occurs.

Will this pump match OEM performance and safety expectations?

KacuYelin produces this module to meet OE design specifications and conducts electrical, pressure and sensor testing prior to shipment. While it aligns with factory standards, follow recommended maintenance and installation steps for best performance and long-term reliability.

• Manufactured to match OEM form, fit, and connector locations.
• Factory-style testing for electrical, pressure, and sensor outputs.
• Recommended to replace fuel filter and clean tank during service.
• Contact KacuYelin support for fitment or troubleshooting questions.
