LS Fuel Pump for Corvette Engine Swaps
When converting a classic C4 Corvette to an LS powerplant, fuel delivery stability at sustained high rpm is critical and this Walbro 255 LPH in-tank pump delivers consistent flow from idle to full throttle. It drops directly into the factory fuel tank and connects to original hard lines without cutting or extra adapters to maintain GM routing and reduce installation time. Crafted in the USA from corrosion resistant alloys and engineered polymers the assembly resists ethanol blends and avoids pressure spikes or cavitation even under heavy acceleration. Installers working on both street driven and track focused LS swaps will appreciate the preserved factory access panel orientation and the reduced risk of vapor lock on hot days.
Immersed Pump Design for Temperature Controlled Fuel Delivery
The Walbro 255 LPH in tank fuel pump is positioned directly inside the Corvette tank to ensure the motor remains fully submerged in fuel at all times. This placement leverages the liquid as a heat sink to prevent internal overheating and avoids the risk of vapor formation that can rob power under sustained high rpm. By relying on continuous fluid immersion, the assembly delays the onset of fuel cavitation and preserves stable pressure output even during extended track sessions. Reaching beyond idle speeds to full throttle, the design supports both LS and original L98 engines with consistent flow and balanced mixture control. Routine maintenance intervals are lengthened thanks to cooler operating temperatures and reduced stress on bearings and seals.
Precise Corvette Fitting Alignment for Seamless Integration
This pump arrives with a Corvette specific fitting set molded to match the factory hard line ports exactly, eliminating the need for splicing or aftermarket adapters. Installers retain the original GM tank routing, avoiding time spent modifying access panels or trimming frame shrouds. The secure, clip style connections hold firm under heavy acceleration and cornering loads, reducing the chance of leaks or loosening over time. By keeping the stock orientation intact, fuel system diagnostics and future service remain straightforward for both street vehicles and competition builds. The result is a professional grade installation that looks factory fresh and performs reliably from the first start through dyno sessions.
USA Crafted Alloys and Engineered Polymers Ensuring Corrosion Resistance
Every internal housing component and fitting is manufactured in the United States from corrosion resistant metals and engineered plastic compounds selected for modern ethanol blends. These materials maintain precise tolerances despite constant exposure to fuel chemistry and wide temperature swings. The robust metal alloys resist rust and stress cracking, while the polymer elements prevent chemical degradation that can lead to leaks or flow restrictions. Quality control in machining and molding processes guarantees a consistent seal surface and long term dimensional stability. Together, these attributes deliver durable performance that stands up to aggressive driving and frequent cold starts.
Complete Swap Kit Streamlining LS and L98 Engine Configurations
As a full swap kit, this assembly pairs the Walbro 255 LPH pump with all fittings needed to mate directly to the matching 255 LPH fuel line and regulator system. Builders gain a unified solution for either an LS conversion or reinstallation of the original L98 powerplant. Providing matched flow capacity across every connection preserves the pump's rated output from idle transitions through wide open throttle. Coordinated component selection reduces part number confusion and idle time spent sourcing compatible hardware. Overall project timelines are tightened, and on-vehicle testing becomes a plug and play process from first fire to final calibration.
Engineered for a precise fit and lasting performance, this fuel pump supports reliable operation during every stage of your LS swap.
