autoexact Fuel Pump Assembly for 1997–2000 Chevy GMC C/K Trucks — Direct-Fit with Sending Unit & Pressure Sensor

AutoExact fuel pump assembly that replaces factory units in compatible 1997–2000 Chevy and GMC C1500/K1500, C2500/K2500, C3500/K3500 trucks to restore stable fuel delivery and gauge sending functions.

When a pickup shows hard starts, hesitation under load, or an inaccurate fuel gauge, a worn pump assembly is often the cause. This AutoExact assembly is made as a direct-fit replacement for specified 4.3L, 5.0L, 5.7L and 7.4L models from 1997–2000 and includes the sending unit and fuel pressure sensor to match OEM mounting and electrical connectors.

How will this pump assembly improve drivability?

Replacing a failing pump assembly helps restore consistent fuel pressure and flow, which reduces stalling, rough idle, and hesitation during acceleration. The assembly’s internal components are sized to meet original flow requirements so the engine receives steady fuel under typical driving conditions.

• Direct-fit design retains factory flow rate and pressure characteristics
• Helps eliminate hard starts and intermittent power loss
• Includes sending unit for accurate fuel level readings
• Built-in filtration lowers contaminant transfer to injectors

What features help protect the pump and fuel system?

This unit uses multi-layer filtration ahead of the pump core to trap rust, dirt, and other debris before they reach internal components. Cleaner fuel entry reduces clogging of the pump and downstream injectors, helping the entire fuel system remain reliable longer.

• Multi-stage sock and internal filter elements capture sediments
• Optimized pickup geometry reduces fuel starvation at low tank levels
• Sealed electrical connections and tested seals limit leak risk
• Pre-shipment testing verifies flow, electrical function, and sealing

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

The AutoExact assembly is designed to match the factory mounting points, harness connector, and tank interface for the listed models, making it a largely bolt-in swap when the correct OE match is confirmed. Before ordering, compare your original part numbers and the connector arrangement to the replacement’s compatibility list.

• Intended for 1997–2000 Silverado/Sierra and C/K series trucks with 4.3L–7.4L engines
• Replaces P74757M, E3947M and other listed OEM numbers
• No cutting or major wiring changes expected when matched to vehicle
• Confirm part number, connector, and tank style prior to purchase

How durable and supported is this replacement part?

AutoExact units undergo functional checks for fuel flow, leak resistance, and electrical performance before shipment. They are built with durable internals suited for heavy-use trucks and backed by a one-year limited warranty and customer support for fitment or performance questions.

• Quality control testing on every assembly prior to shipping
