GDUKOP Electric Fuel Pump Assembly for 1989–1996 Chevy Corvette 5.7L V8 — HP10031 with Sending Unit & Hardware

GDUKOP HP10031 is a complete electric fuel pump assembly with an integrated sending unit designed to replace the original pump in 1989–1996 Chevy Corvette 5.7L V8 models.

This all-in-one replacement restores fuel delivery and level sensing in classic Corvettes without the need to source separate parts. The assembly includes the pump motor, fuel level sending unit, inlet strainer, and the hardware required for installation, matching the OE fitment codes so it integrates directly with the factory housing and wiring. Built to meet or exceed the performance of the original unit, it aims to deliver steady pressure and dependable flow for everyday driving and restoration projects.

Will this pump fit my Corvette model and year?

Yes — the GDUKOP HP10031 is engineered specifically for 1989 through 1996 Chevrolet Corvette models equipped with the 5.7L V8 engine. It corresponds to multiple OE replacement numbers so it matches the factory interface and mounting points for these years.

• Compatible years: 1989–1996 Corvette with 5.7L V8
• OE cross-references: HP10031, 19179534, 25027510, 25116881, E16008, P74074, RE0381P
• Includes sending unit to preserve fuel level readout accuracy
• No modification required when replacing like-for-like assemblies

How does the complete assembly simplify installation?

Because the unit ships with pump, sending unit, strainer, and mounting hardware, you avoid hunting down separate components or adapters. The plug-and-play design aligns with factory connectors and seals, which helps shorten workshop time and reduces the chance of compatibility errors.

• Pre-assembled components minimize bench work before installation
• Includes strainer and necessary hardware for a direct swap
• Factory-style electrical and fuel fittings for easier reconnection
• Reduces parts sourcing and troubleshooting after replacement

What performance and durability features should I expect?

The GDUKOP assembly uses precision-engineered parts and corrosion-resistant materials designed to maintain consistent fuel pressure and flow. Each unit is tested before shipping to verify operation under load and to help prevent common failure symptoms like hard starts or stalling caused by fuel delivery problems.

• Engineered for steady pressure and reliable flow rates
• Durable materials to resist corrosion and wear over time
• Factory-equivalent pump motor and sending unit calibration
• Quality-tested units to reduce early-life failures

What maintenance or compatibility checks should I do before replacing the pump?

Before installation, verify your Corvette’s engine size and model year to ensure correct fitment. Inspect the fuel flange, wiring harness and tank for damage or heavy corrosion — replacing compromised connectors or seals will improve reliability and safety after the swap.

• Confirm 1989–1996 model year and 5.7L V8 engine designation
• Check tank flange and sealing surface for warping or residue
• Inspect wiring and connectors; replace brittle or corroded leads
• Replace fuel filter if suggested by vehicle maintenance schedule

Who is this for: The GDUKOP HP10031 assembly is aimed at Corvette owners, restorers, and mechanics seeking a reliable, direct-fit replacement for aging or failed fuel pumps on 1989–1996 5.7L V8 models. It’s also a practical choice for anyone restoring original fuel system performance or replacing a noisy, weak, or intermittently operating pump without modifying factory hardware.
