Stainless Steel Tank Construction for Corrosion Resistance

The fuel tank shell is crafted from heavy-gauge stainless steel, offering exceptional resistance to rust and chemical attack. This material choice ensures the tank retains its strength and appearance even when exposed to ethanol blends and road salts. By avoiding softer metals, the design maintains dimensional stability under thermal stress, reducing the risk of leaks or deformation. Over years of service, you'll appreciate the tank's ability to withstand harsh conditions without requiring frequent maintenance.

255 LPH Pump Capacity and LS Engine Integration

This kit includes a 255 LPH Walbro pump rated to support engines up to 550 hp, delivering a consistent supply of fuel under demanding throttle conditions. Precise internal calibration of the in-tank module optimizes pressure control, which sharpens throttle response and minimizes fuel starvation during cornering or acceleration. Compatibility with LS engine swaps makes this assembly an ideal match for modern powerplants installed in the 1965-1966 Impala or Caprice. The robust pump ensures your EFI system runs reliably whether you're cruising the boulevard or pushing the limits on the track.

Precision Fitment and Complete Kit Simplifies Installation

Every required component - including tank straps, filler neck, vent filter, gaskets, and hardware - is provided in the kit, eliminating trips to the parts store and reducing installation time. Detailed alignment of inlet and outlet ports ensures seamless connection to existing fuel lines and sending units. Even for a home garage project, the straightforward drop-in replacement process means you'll be back on the road quickly with a secure, leak-free setup.
