1964-1967 Chevy Chevelle LS Swap EFI Fuel Tank Kit with 255 LPH Pump
When an LS swap in your vintage Chevelle pushes factory fuel systems beyond their limits the 1964 through 1967 Chevelle EFI Fuel Tank Kit with 255 LPH Pump supplies a constant flow to support spirited acceleration and tight fuel pressure control. Engineered to drop into original mounting points this solution retains stock fuel bay contours without requiring custom brackets or trimming. The submerged Walbro pump operates cooler and maintains steady fuel pressure under heavy throttle to reduce vapor lock risk. Complete hardware including tank straps gaskets and a vent filter ensures a clean assembly from start to finish.
Submerged Pump Design for Consistent Pressure
The Walbro module lives fully inside the tank, allowing the pump to run cooled by surrounding fuel and maintain a stable output even under hard acceleration. Its 255 LPH flow capacity supports engines up to 550 HP and resists vapor lock by avoiding heat soak. By replacing only the tank internals, this solution keeps original routing and clearance intact for a seamless fit. The result is reliable fuel delivery and sustained pressure control throughout spirited driving conditions.
Direct Fitment in Original Fuel Bay
Every contour and mounting point of the 1964 through 1967 Chevelle fuel bay is preserved with this tank design. Installers use existing brackets and body holes without trimming sheet metal or fabricating custom supports. The filler neck and vent filter align precisely where the factory components once sat, keeping external lines clean and original. This direct fit approach ensures a professional appearance beneath the car while maintaining structural integrity.
Calibrated Sending Unit for Accurate Gauge Response
Precision engineering gives the sending unit the same resistance curve and float action as the original, delivering accurate fuel level readings to the dash. Robust wiring and a corrosion-resistant arm maintain smooth electrical contact over years of use, preventing false empty warnings. Drivers benefit from a linear gauge response that reflects true tank volume, improving trip planning and reducing stress during long drives or track sessions.
Comprehensive Hardware Package Speeds Assembly
This all-in-one kit includes tank straps, gaskets, vent filter, filler neck and all necessary fittings, so builders never need to hunt for compatible parts. Step-by-step instructions outline precise gasket placement and torque values to guarantee leak-free sealing from the start. With every component accounted for, installs move quickly and deliver professional quality that stands up to daily driving demands and high-load scenarios alike.
