LS and LT Swap Fuel Tank Kit for 1968-1970 Pontiac GTO/Lemans A-Body
When fitting an LS or LT powerplant into a 1968 to 1970 GTO or Lemans A Body, this EFI fuel tank kit addresses cramped underbody space and sustains high demand engine fueling. Precision formed contours carve clearance around exhaust tubes and rear suspension links without modifying structural walls. Engineered with an integrated 400 LPH Walbro pump, it maintains consistent pressure even under cornering force to prevent cavitation in spirited driving. Complete mounting hardware aligns with original points to simplify assembly and ensure accurate fuel level data for swap installations.
Precision Formed Notched Tank Profile
The tank's precision formed notched contour creates dedicated clearance pockets around exhaust headers and rear suspension links to prevent interference without trimming structural members. Maintaining consistent wall thickness at each cutout safeguards against heat soak and stress cracking under rigorous driving conditions. This precise shaping preserves the original floorpan geometry so installers can avoid complex sheet metal modifications and uphold the factory mounting angles. By carving space rather than removing material from the chassis, this design retains full fuel capacity and ensures optimal chassis alignment. The result is a professional fit that streamlines the swap and maintains the A Body's original underbody appearance.
Submerged Walbro Pump for Consistent Delivery
Positioning the 400 liter per hour Walbro pump fully submerged within the tank guarantees a constant flooded inlet even during high g cornering or hard acceleration maneuvers. Drawing fuel directly from the base reduces internal operating temperatures and helps maintain uniform pressure for high engine output scenarios, including applications over 550 horsepower or forced induction. Submerged installation also dampens pump noise and vibration before it reaches the cabin, improving driver comfort on long runs. The reliable pump architecture delivers precise flow under rapid throttle changes, sustaining injector calibration and preventing lean spikes. With proven service life in demanding environments, it supports sustained performance for track or street duty.
Comprehensive Mounting Kit for Seamless Integration
The comprehensive installation kit includes a factory calibrated sending unit, tank straps, filler neck, vent filter, gaskets and precision hardware engineered to match original mounting points. Each steel bracket and seal is laser measured to align without trial fitting, so technicians avoid hours of mock up and custom bending. Accurate fuel level data from the calibrated sending unit improves gauge fidelity and helps drivers plan refueling stops during extended trips. Integrated vent filtration manages internal pressure and blocks contaminants, protecting pump and injectors from debris. This kit approach eliminates missing components and streamlines the entire LS or LT conversion process.
Robust Steel Fabrication for Lasting Durability
Constructed from heavy gauge steel plate, the tank resists deformation caused by road impacts, aggressive cornering loads and temperature cycles without suffering stress fractures. Precision welded seams reinforce critical junctions, creating a leak proof vessel that maintains structural integrity under high load cycles. The robust steel fabrication withstands moisture and debris exposure, ensuring reliable operation over many seasons even without additional surface treatment. By avoiding thin stamped metal designs, this tank delivers secure containment of volatile fuel and protects occupants from vapor intrusion. Its sturdy build provides peace of mind and service life that aligns with the demanding requirements of LS or LT engine installations.
