LS Swap Fuel Pump for 1984-1991 Corvette
When swapping an LS into a 1984-1991 Corvette, consistent fuel delivery under sustained high rpm is vital and this Corvette tank pump meets that requirement by maintaining proper pressure from idle to full throttle. It drops into the factory tank and mates with original hard lines without adapters while using continuous fluid cooling to prevent heat buildup and pressure spikes. Built in the USA from corrosion resistant alloys and polymers, it handles modern ethanol blends and reduces the chance of vapor lock or cavitation. Installers benefit from preserved factory routing and matched fittings that streamline setup and ensure leak proof performance on street or track.
Immersed Pump Design for Stable Pressure
The Walbro 255 LPH in-tank fuel pump mounts inside the factory tank ensuring continuous fluid cooling and pressure dampening. Operating immersed in fuel, the unit avoids heat buildup that can cause local vapor expansion and lean conditions during spirited driving. This internal placement also isolates the pump from engine bay heat and reduces risk of vapor lock when ambient temperatures climb. Consistent delivery from idle through redline maintains a safe air fuel ratio for both LS swaps and original L98 engines. The design supports sustained high rpm and heavy loads while extending service intervals to keep projects on schedule.
Direct Connection to Factory Fuel Lines
The precision molded fitting set aligns exactly with the original hard line ports within the C4 Corvette tank. Eliminating the need for cutting or aftermarket adapters, this arrangement preserves GM's factory routing and safety features. Installers can retain the stock access panel orientation and avoid trimming plastic shrouds, reducing installation errors. Secure engagement under cornering forces and heavy acceleration ensures leak free operation on both street and track. By using OEM style connectors, the pump integrates seamlessly with existing plumbing for a clean professional finish.
USA Crafted Alloys and Engineered Polymers
Every internal component is crafted in the USA from alloys and engineered polymers chosen for their resistance to corrosion and chemical attack from modern fuel blends. These materials maintain dimensional stability even when exposed to ethanol additives, ensuring consistent clearances inside the pump housing and fittings. The robust metal and polymer combination reduces wear from vibration common in performance applications. Strict quality control during machining and molding delivers repeatable fit and finish. The result is a durable assembly that maintains flow characteristics over extended service intervals and qualifies for extended warranty support from the manufacturer.
Integrated Kit for Streamlined Installation
This assembly arrives as a complete swap kit with the Walbro 255 LPH pump and a tailored set of connectors designed to mate directly with the matching 255 LPH fuel line and regulator system. By bundling these components, builders avoid multiple part numbers and downtime spent sourcing compatible hardware. The unified approach guarantees matched flow capacity across all connections, preserving the pump's rated output from idle to wide open throttle. Whether retaining the factory engine or upgrading to an LS family unit, installers gain a single solution that simplifies logistics and on-vehicle testing. The coordinated design keeps project timelines tight and delivers reliable fuel delivery from first start to final tune.
Engineered for reliable pressure and a precise fit in your LS swap.
