1963-1967 Chevy Corvette LS EFI Fuel Tank Kit 255 LPH Pump
When you blend a modern LS engine with a 1963 through 1967 Corvette the fuel system must match its performance demands and this EFI tank kit delivers a 255 LPH flow to support up to 550 horsepower. Built from corrosion resistant steel the tank slips into the original Y Body frame brackets for a direct fit that requires no chassis modification. By keeping the pump submerged in cool fuel the kit reduces vapor lock during spirited driving and maintains reliable fuel delivery for both street and track use. The package includes the in tank pump module sending unit and all required hardware so installation follows factory steps and avoids trips back to the parts bin.
Immersed Pump Design Minimizes Vapor Lock
At the heart of this fuel kit is a Walbro pump that remains fully submerged in the reservoir. By drawing cool fuel directly, it greatly lowers the chance of vapor formation under sustained load. This steady delivery helps prevent lean conditions and erratic throttle response during spirited driving. As a result, engine performance remains consistent even in hot conditions or long track runs.
Precision Fitment for Y Body Corvette Frames
The replacement tank is formed from corrosion resistant steel to match the contours of 1963 through 1967 Corvette underbodies. It utilizes the original Y body mounting brackets so no cutting or altering of the chassis is needed. Filler neck and vent filter align with the stock body openings to preserve the vehicle's classic appearance. This faithful alignment protects structural integrity and ensures the installation looks as if it came from the factory.
Complete Kit Provides All Essential Fuel Components
Every necessary part is included to streamline the swap, from the pump and in tank module to the sending unit and hardware. Tank straps, filler neck and vent filter arrive ready to install alongside gaskets and fasteners. By following the sequence of included components, installers can avoid repeated trips to the bench for missing fittings. This approach reduces the chance of fuel leaks and speeds up the build process for both professional shops and experienced enthusiasts.
Sustained Flow for 550 HP LS Engine Upgrades
With a 255 liter per hour flow rate, this kit supports LS engines making up to 550 horsepower without strain. It delivers ample volume at wide throttle openings to maintain power delivery under hard acceleration. Whether on the street or track, the system keeps pressure stable at high rpm. Builders gain confidence knowing the pump can handle future performance upgrades without compromise.
