Complete Fuel Pump Module Assembly

Unlike replacing only the pump motor, this complete module assembly includes:

• Fuel pump
• Sending unit
• Integrated pressure sensor
• Housing assembly

This helps restore:

• Accurate fuel level readings
• Consistent fuel pressure
• Reliable engine startup
• Smooth vehicle operation

Because replacing a worn-out fuel pump while keeping a failing sending unit is simply creating future work.

Common Fuel Pump Failure Symptoms

As GMT800 trucks age, common fuel pump issues include:

• Long crank times
• Hard starting
• Poor acceleration
• Hesitation under load
• Stalling
• Low fuel pressure
• Crank-no-start conditions

These symptoms become especially noticeable while:

• towing
• hauling heavy loads
• climbing grades
• driving in hot weather

Restores Proper Fuel Delivery

Proper fuel pressure is critical for:

• Vortec engines
• Flex Fuel applications
• Heavy-duty towing
• Daily driving reliability

This assembly helps restore:

• Factory fuel pressure
• Consistent injector performance
• Smooth idle quality
• Reliable startup behavior

Even a healthy 6.0L or 8.1L engine performs poorly when fuel pressure drops below specification.

OE-Style Direct Fit Installation

Designed as a direct replacement, this module features:

• Factory-style connectors
• OEM mounting locations

No custom wiring or modifications are required.

• Restoration projects

Many GMT800 owners intend to keep their trucks indefinitely, making preventative fuel system maintenance a smart investment.

4. Removing the original module
5. Installing the replacement assembly
