1955-1956 Chevy 150/210/Bel Air/Delray LS and LT EFI Fuel Tank Kit with 400 LPH Pump
Engine swap projects on 1955 to 1956 Chevy 150, 210, Bel Air or Delray models demand precise fuel delivery and perfect fitment. The 1955 to 1956 Chevy EFI Fuel Tank Kit with 400 LPH Pump provides an in tank pump module, sending unit, tank straps, filler neck, vent filter, gaskets and hardware optimized for LS and LT EFI applications. Featuring a 400 LPH fuel pump rated for supercharged or over 550 hp setups with premium fuel, it offers direct fitment to original frame rails and factory openings, preserving stock underbody clearances and ensuring stable flow during sudden throttle transitions. All parts align with factory mounting points to minimize layout work and secure reliable operation.
Precision Design for Classic Chevy Fitment
The 1955 and 1956 Chevy EFI fuel tank kit with 400 LPH pump is engineered to match the frame contours and underbody layout of Chevy 150, 210, Bel Air and Delray models without any trimming. Its tailored geometry ensures that factory mounting points for fuel lines, sensors and mounting feet are preserved. This seamless fit reduces installation time, retains factory venting paths and avoids leak points, giving installers confidence that the swap from mechanical feed to modern EFI proceeds without alteration to frame rails or body panels.
High Capacity Fuel Delivery System
At the core of this assembly lies a 400 LPH Walbro electric fuel pump optimized for premium grade fuel. It sustains constant pressure in applications over 550 horsepower and has proven durability in supercharged environments where demand can spike instantly. By maintaining stable flow at high RPM it prevents lean conditions that can cause detonation and heat damage. The pump's internal regulator isolates fluctuations caused by injector pulses so rail pressure remains within plus or minus two psi even during rapid throttle shifts. This precision supports consistent atomization from LS or LT injectors and delivers a constant air fuel mixture under wideband control.
Durable Construction and Efficiency Gains
Manufactured entirely with steel and poweder coated for years of service.
