1984-1991 C4 Corvette Fuel Delivery with 255 LPH LS Pump

Ensure unwavering fuel pressure in your C4 Corvette under aggressive acceleration with the precision-engineered Walbro 255 LPH tank pump and Corvette specific fittings that install into the factory tank and lines without cutting or extra hardware. Made in the USA from corrosion resistant materials, this complete solution maintains rich mixtures for stock L98/LT1 setups or LS conversions while delivering consistent reliability.

High-Flow LS Fuel Pump Kit for Engine Swap Applications

Installing an LS engine into a C4 Corvette often exposes the factory pump's limits and this 255 LPH fuel pump kit resolves that by fitting directly into the stock tank. The Corvette specific fittings engage original lines without cutting or adapters, preserving the factory routing and reducing install time for both home builders and technicians. Housed inside the tank to benefit from fluid cooling and dampening, the Walbro unit maintains precise pressure during hard pulls or prolonged high rpm, guarding against lean spots that can threaten engine health. Crafted in the USA from corrosion resistant materials, this assembly delivers dependable service whether you run a stock L98/LT1 or complete an LS conversion.

Consistent Fuel Flow Under Demanding Driving

The Walbro 255 LPH pump is engineered to maintain a stable volume of fuel even when engine demand spikes during full throttle or sustained high rpm. By operating inside the tank, the pump benefits from a constant supply of fuel that cools internal components and dampens pressure fluctuations, reducing the risk of lean conditions that can damage pistons and valves. This design ensures the mixture remains optimal across a wide range of driving scenarios, whether you're launching out of a corner or holding top speed on a strip. Technicians and home builders alike gain peace of mind knowing the system delivers uniform performance under extended stress.

Direct Fit Integration with C4 Corvette Tank

This kit installs effortlessly into the stock C4 Corvette fuel tank, eliminating the need for cutting, aftermarket adapters, or rerouting hard lines. Precision molded fittings align with original line ports, preserving the factory routing that Corvette engineers optimized for safety and ease of maintenance. Retaining the stock layout not only protects resale value but also simplifies future service by keeping all standard connections intact. The secure engagement of the fittings prevents leaks and movement, even under hard cornering or aggressive acceleration.

Durable Materials Resisting Ethanol and Additives

Every fitting and housing is crafted from corrosion resistant alloys and engineered polymers chosen to withstand modern fuel formulations, including ethanol blends and potent additives. Manufactured in the USA under strict quality control protocols, these components deliver uniform dimensional accuracy and structural integrity. This robust construction limits chemical attack and minimizes vibration-induced wear, helping to extend the service intervals of the entire system. Featuring American made parts also ensures rapid replacement availability and consistent build quality.

Purpose Built Kit for Streamlined LS Conversions

Beyond the core Walbro pump, the kit includes a tailored set of fittings designed to mate with a matching 255 LPH fuel line and regulator assembly. By unifying pump, connectors, and regulator interface, the solution removes uncertainty over part compatibility and prevents last minute trips for missing hardware. Installers benefit from a cohesive system engineered to flow the correct volume of fuel across the rpm range, keeping build schedules on track. This focused approach delivers a ready to run upgrade whether you're swapping an LS into the factory L98/LT1 platform or performing a full conversion.

Engineered for a precise fit and dependable performance in any LS swap, this fuel pump kit offers the reliability you need for consistent engine health.
