LS and LT EFI Fuel Tank Kit with 400 LPH Pump for 1968-1970 GTO/Lemans
When transplanting an LS or LT engine into a 1968 to 1970 GTO or Lemans, ensuring a steady, cavitation-free fuel supply under aggressive cornering conditions is essential for consistent engine performance. The tank's precision formed contours carve dedicated clearance pockets around exhaust tubes and rear suspension links without altering the factory floorpan or sacrificing fuel capacity. Fabricated from heavy gauge steel and reinforced with precision welded seams, it resists deformation from road impacts and sustained load cycles while maintaining leak proof integrity. An integrated 400 LPH Walbro pump remains submerged to guarantee a flooded inlet during hard accelerations or lateral loads and the complete mounting kit aligns with original points for accurate fuel level readings on your LS or LT swap.
Notched Profile for Unobstructed Exhaust and Suspension Clearance
The notched fuel tank profile carves precise pockets around exhaust tubes and suspension links, eliminating interference points and preserving full fuel capacity. By forming dedicated clearance instead of cutting the floor pan, the design upholds original underbody geometry and mounting angles. Consistent wall thickness at each notch guards against heat soak and stress cracking during spirited driving. This attention to contour detail simplifies installation and delivers a seamless fit in the 1968 to 1970 A Body environment.
Submerged Fuel Pump Placement for Cavitation Resistance
Positioning the 400 LPH Walbro unit fully below the fuel surface ensures a flooded inlet under lateral load or hard acceleration, eliminating cavitation risks. Direct draw from the tank base lowers pump temperature and sustains uniform pressure for forced induction or over 550 horsepower applications. Submerged installation attenuates pump noise and vibration, improving cabin quietness. This proven configuration delivers steady flow to match injector requirements and prevents lean spikes during rapid throttle changes.
Complete Fuel System Kit for LS and LT Conversions
This all in one fuel system kit includes the Walbro pump module, sending unit, tank straps, filler neck, vent filter, gaskets and precision hardware, eliminating missing parts. Each component aligns with original mounting points, assuring accurate fuel level reading and correct orientation without custom fabrication. Integrated vent filtration maintains safe internal pressure and blocks debris that could harm injectors or the pump. This kit approach streamlines the swap process, reduces installation time and enhances reliability.
Heavy Gauge Steel Fabrication for Impact Resistance
Fabricated from heavy gauge steel, the fuel tank resists deformation from road impacts, cornering forces and vibration, preserving its shape under sustained load cycles. Precision welded seams reinforce critical junctions, creating a leak proof vessel that withstands pressure variations and temperature cycles without stress fractures. By avoiding thin stamped materials, the design protects against punctures and minimizes vapor intrusion into the cabin. This robust construction offers long term durability and peace of mind for high output engine installations.
