LS EFI Fuel Tank Kit with 255 LPH Pump for 1968-1970 Pontiac GTO
Swapping an LS engine into a 1968 to 1970 Pontiac GTO or Lemans often exposes the original tank's limited capacity under high demand. This Fuel Tank Kit featuring a 255 LPH pump delivers consistent flow up to 550 hp and mounts directly to the factory points for a no-modification fit. Crafted from heavy gauge steel and supplied with all necessary fittings and connectors it resists corrosion while streamlining plumbing and wiring tasks. By retaining stock mounting locations within the A body frame it preserves chassis alignment and safeguards suspension clearance when pushing the LS powerplant.
Factory Mount Ready Design for Precision Alignment
This fuel tank kit is molded to match the original frame rails on 1968 to 1970 Pontiac GTO and Lemans models, enabling a direct fit into factory mounting points. By preserving the stock geometry technicians maintain correct frame alignment and ground clearance while avoiding interference with suspension components. This minimal fuss approach reduces cycle time on the lift. The exact replication of mounting profiles also ensures that weight distribution remains consistent with the original design, which contributes to predictable handling under load. This approach also eliminates the need for costly fabrication work to alter the chassis or to create adapter brackets.
Engineered Fuel Delivery with In Tank Pump Module
The 255 liter per hour Walbro pump mounted inside the tank delivers a steady flow that supports engines producing up to 550 horsepower. Its internal pickup design draws fuel from multiple angles within the reservoir, helping to prevent vapor lock during aggressive cornering or steep grades. Consistent pressure simplifies calibration and yields reliable throttle response under sudden load changes. This reliability in fuel delivery is critical when dialing in tuning maps or when pushing the powerplant in track or street driving. Installing the in tank module also keeps noise and heat inside the enclosure, which promotes cooler operation and reduces cabin buzz.
Premium Steel Fabrication for Long Service Life
Constructed from premium gauge steel, the replacement tank offers robust resistance to corrosion from moisture and road debris. The rigid structure resists deformation even when subjected to full loads, preserving uninterrupted flow. An internal surface treatment prevents sediment accumulation and moisture ingress, reducing the need for frequent filter replacements and extending maintenance intervals. With its combination of strength and protective layers, this tank maintains stable fuel pressure and supports long term reliability for daily use or spirited driving. Engineers designed the steel gauge to withstand road impacts and resist denting, an important factor when driving on rough surfaces or encountering debris.
Complete Kit Packaging Streamlines Installation Workflow
This comprehensive kit combines the pump module, sending unit, filler neck, vent filter, straps, gaskets and fastening hardware into a single package. Components are pre fitted with connectors and standardized interfaces to eliminate compatibility issues and to speed the plumbing and wiring process. The cohesive layout gives fabricators confidence that all parts align correctly on first assembly. By reducing parts sourcing and test fitting, the kit cuts shop time and helps achieve a professional level finish on every conversion. Every kit component is tested for fit and finish before packaging, ensuring that replacement parts meet the same dimensional tolerances as original GM items.
