LS EFI Fuel Tank Kit with Notched 255 LPH Pump for 1968-1969 Chevy Chevelle
Projecting a modern LS powerplant into a 1968 to 1969 Chevelle A Body can lead to interference between a stock fuel tank, exhaust headers, and rear tire travel. To solve these clearance challenges, the EFI Fuel Tank Kit with Notched 255 LPH Pump features a notched tank design carved to clear suspension movement and exhaust routing while housing a Walbro pump delivering 255 liters per hour flow for up to 550 horsepower. Mounting to factory brackets and tying into stock fuel lines, it reduces installation time and cuts fabrication work. Whether street cruising or hauling out on track days, this steel tank design ensures consistent fuel pressure and protects against contact with exhaust pipes.
Precision Notched Tank Design for Clearance
The notched contour along the tank's lower rail carves out vital space for modern exhaust headers and rear wheel movement after an LS swap. By selectively removing material only where required, it maintains the original fuel capacity while preventing contact during full suspension travel. This sculpted profile ensures ample clearance under hard cornering or rough road surfaces, keeping the tank protected from abrasion and deformation. The result is a seamless integration that preserves chassis geometry without added fabrication.
Integrated High-Flow Walbro Pump for Consistent Delivery
At its core, this kit features a 255 LPH Walbro pump engineered to support up to 550 horsepower applications. Encasing the pump inside the tank shields it from engine heat and road debris, which helps prevent vapor lock and extends service life. The precision rotor assembly sustains steady pressure under wide-open throttle, eliminating lean spots during aggressive acceleration. Whether navigating city streets or lapping the track, this design keeps fuel delivery reliable at every RPM.
Robust Steel Construction with Internal Baffles
Fabricated from heavy-gauge steel with a corrosion-resistant finish, the tank stands up to ethanol blends and moisture exposure common in both street and track environments. Internal baffles control fuel movement to keep the pump inlet submerged during sharp turns and heavy braking, preventing starvation and reducing the risk of cavitation. This sturdy shell also resists dents from road debris, ensuring dependable operation season after season.
Direct Fit with Factory Bracket Integration
This fuel tank kit reuses original mounting brackets and stock hose connections to streamline installation on a 1968 to 1969 Chevelle. By matching standard inlet and outlet locations, it eliminates the need for custom lines or adapter brackets. Most installations can be completed in a single afternoon using basic hand tools, reducing downtime and project cost. The outcome is a clean, factory-style setup that preserves chassis integrity and ensures lasting fuel-system reliability.
