EFI Fuel Tank Kit for 1968-1969 Chevy Chevelle A-Body LS/LT Swaps
Swapping an LS or LT powerplant into a 1968 to 1969 Chevelle A body can overwhelm the factory fuel system and the EFI Fuel Tank Kit with 400 LPH pump delivers the flow needed for engines above 550 horsepower. The in tank assembly combines pump sending unit and filler neck in a single package and bolts to factory crossmembers so no cutting or welding is required. Precise baffles and supplied hardware maintain steady inlet pressure under hard acceleration and preserve chassis clearance for street and track applications.
Direct Fit Installation for 1968-1969 Chevelle A-Body
The EFI fuel tank kit is engineered to bolt directly to the factory crossmembers of a 1968 to 1969 Chevelle A-body, eliminating any need for cutting or welding. Its tank shell and strap locations mirror the original configuration, allowing installers to maintain the classic underbody profile and chassis clearance. All required straps, gaskets and mounting hardware are included in the kit, so assembly is straightforward even for those with basic tools. By preserving the factory mounting points, this direct fit solution saves hours of labor and protects structural integrity. It also ensures proper alignment with suspension components for reliable street and track use.
Integrated In-Tank Fuel Assembly Simplifies Setup
This kit features a single in-tank module that houses the 400 LPH pump, sending unit, vent filter and filler neck in one preassembled package. Factory-sealed gaskets and precisely machined sealing surfaces minimize potential leak points, letting the installer focus on plumbing and electrical connections. Consolidating multiple components into a single unit reduces part count and eliminates adapter requirements, cutting setup time. The modular approach also guarantees that fuel lines and wiring ports are positioned optimally for a clean underbody installation. As a result, even first-time installers achieve a professional result without hunting for separate fittings and brackets.
400 LPH Walbro Pump Ensures Steady Fuel Supply
At the heart of this kit lies a 400 LPH Walbro pump designed for engines producing more than 550 horsepower, including forced-induction LS and LT applications. Its high flow capacity prevents fuel starvation under hard acceleration and maintains consistent pressure during sustained track runs. Built in the USA, the pump module delivers reliable performance and resists vapor lock, even in demanding thermal environments. By providing a continuous flow rate, it supports modern high output powerplants and ensures the engine ECU receives accurate fuel data. This dependable supply is critical for preserving engine health and maximizing throttle response.
Precision Baffle Design for Consistent Pressure Under G-Forces
Internal baffles within the tank are strategically positioned to manage fuel movement and prevent sloshing during cornering and braking. This layout maintains a steady inlet pressure at the pump pick-up, avoiding momentary fuel starvation when lateral loads shift fuel away from the feed port. The robust baffle system also preserves chassis clearance, so it does not interfere with rear suspension travel or ground effects. Combined with the vent filter and filler neck integration, the design guarantees that fuel delivery remains uninterrupted on both spirited street runs and competitive track days. Installers benefit from a ready-to-go package that delivers consistent performance under real-world conditions.
