EFI Fuel Tank Kit for LS Swaps in 1955-1956 Chevy 150/210/Bel Air/Delray
Fitting an LS engine into a 1955 or 1956 Chevy 150, 210, Bel Air or Delray often hits a fuel delivery wall and the 1955-1956 Chevy EFI Fuel Tank Kit - 255 LPH Pump moves the pump inside a steel tank to hold steady pressure. Enclosing the unit in a stamped housing cuts external plumbing, preserves underbody clearance and prevents heat soak from the engine bay. Including the 255 LPH pump module ensures stable flow for engines up to 550 horsepower while precision mounting points align with factory rails, posts and filler openings for a direct fit that saves time and delivers precise throttle response at any rpm.
Internal Pump Integration Enhancing Fuel Delivery Stability
Locating the pump module inside the fuel tank housing removes the need for long feed lines along the frame and cuts out pressure loss that happens over external runs. Isolating the Walbro unit within the steel container also protects it from heat in the engine bay and prevents heat soak from thinning fuel at high temperature. By housing the pump in a sealed environment, this design preserves factory underbody clearance and avoids modifications for ground height. The result is a uniform fuel supply under all driving conditions and a more immediate throttle response at mid and high rpm. Installers benefit from fewer plumbing connections to worry about and drivers enjoy consistent pressure throughout the rev range. Overall, in tank integration delivers both reliability and performance for LS conversions.
Precision Tank Design for 1955 to 1956 Chevy LS Conversions
This fuel tank is stamped and shaped to match the chassis rails and floor contours of 1955 to 1956 Chevy 150 210 Bel Air and Delray models. Each strap post, filler neck opening and mounting rail aligns with original factory points so there is no need to fabricate brackets or trim metal. The precision stamping ensures uniform clearance around the body and maintains the factory ride height for an authentic appearance. Quick drop in installation saves hours of mock up and adjustment work during a swap project. Careful attention to fitment details also helps maintain tank integrity and prevents vibration or noise when on the road.
255 Liter Per Hour Pump Supporting Up to 550 Horsepower
The integrated Walbro pump delivers a steady 255 liters per hour of flow to support LS engines rated up to 550 horsepower without risk of fuel starvation. This capacity guards against lean conditions under hard acceleration or at sustained high rpm that can lead to detonation or power loss. Consistent flow under load keeps fuel pressure stable, which in turn enables precise injector metering and sharp throttle response at any engine speed. Drivers will notice smooth power delivery and no hesitation when aggressively driving or towing. This pump capacity also leaves headroom for mild tuning upgrades without requiring a secondary fuel system. Overall, the flow characteristics help preserve engine health and performance under demanding conditions.
Complete Kit Streamlining EFI Conversion for Vintage Chevys
This assembly includes the 255 liter per hour pump, in tank module, sending unit, filler neck, vent filter, tank straps, gaskets and all required hardware in one package. Each component arrives pre sized for direct installation so there is no need to hunt for extra gaskets or brackets. The detailed instructions guide technicians through removal of the old tank and mounting of the new assembly using common tools. By eliminating missing parts and guesswork the kit cuts swap time significantly and reduces the risk of leaks or fitment errors. Installers can focus on wiring and calibration rather than fabricating custom pieces. As a result, both professional shops and home garages achieve reliable fuel flow and precise throttle response from day one.
