Swift-Run Fuel Pump Assembly for Chevrolet Silverado 1500 2010-2013 V8 — Full In-Tank Module with Sending Unit & Pressure Sensor

Swift-Run Fuel Pump Assembly E4005M is a direct-replacement in-tank fuel module engineered to restore reliable fuel delivery for Chevrolet Silverado 1500 and GMC Sierra 1500 models from 2010–2013 with V8 engines.

If your Silverado or Sierra is showing fuel-pressure symptoms, rough starts, or inconsistent fuel gauge readings, this Swift-Run assembly is built as a full-module swap to replace the pump, sending unit, strainer, pressure sensor and seal ring in one installation.

The product has been electrically and hydraulically tested to ensure steady flow and sensor feedback for the factory fuel system.

How does the Swift-Run assembly improve fuel system performance?

This assembly replaces the entire in-tank module—pump, sending unit, pressure sensor, strainer and seal—so you get renewed flow rates and consistent sensor signals without mixing aftermarket components. Each module undergoes electrical, pressure and sensor validation to reduce the chance of premature failure and to restore correct fuel pressure to the injectors.

• Complete module replacement avoids compatibility issues between parts
• Pre-tested pump core for stable flow and electrical performance
• Includes strainer and seal ring to protect the pump and tank

What should I do before and during installation?

Before replacing the assembly, drain or lower the fuel level and clean the tank and supply lines to prevent debris from clogging the new module. Follow the included installation instructions and replace the fuel screen periodically to prolong pump life. Proper handling of the electrical connector and O-ring sealing surfaces ensures a leak-free fit.

• Clean fuel tank and lines to remove sediment
• Replace screen/strainer at intervals to avoid clogging
• Use supplied seal ring and follow torque specs for the locking ring
