autoexact Fuel Pump Assembly for 1997–2000 Chevy & GMC Trucks — Sending Unit & Pressure Sensor

AutoExact fuel pump assembly is a direct-replacement module for select 1997–2000 Chevrolet and GMC 4.3L–7.4L trucks, complete with sending unit and fuel pressure sensor to restore reliable fuel delivery.

If your Silverado or C/K-series truck shows symptoms like hard starts, hesitation, or inconsistent fuel gauge readings, a failing in-tank pump or sending unit can be the cause. This AutoExact assembly matches OE mounting points and electrical connectors for a straightforward swap, while its multi-stage filtration and optimized pickup help protect the pump and maintain fuel flow even at low tank levels.

How does this assembly improve engine performance?

Replacing a worn pump restores proper fuel pressure and steady flow to the injectors, which reduces misfires, rough idle, and loss of power. The assembled unit is engineered to provide consistent delivery under typical driving loads for older trucks.

• Engineered to meet factory-style flow and pressure for smoother acceleration
• Multi-layer filter captures rust and larger contaminants before they reach the pump
• Includes fuel pressure sensor to maintain accurate delivery feedback
• Designed to reduce clogging and extend fuel-system component life

Will this part fit my 1997–2000 Chevy or GMC truck?

The AutoExact assembly replaces specific OE part numbers used across many 1997–2000 Silverado and C/K-series models. Fitment depends on tank type, electrical connector, and mounting style, so verifying your original part numbers before purchase is important.
