1969-1970 Impala EFI Fuel Tank Kit with 400 LPH Pump
When fitting an LS powerplant into a 1969-1970 Impala, sustaining consistent fuel pressure becomes critical, and this EFI fuel tank kit addresses that need by combining a deeper steel reservoir with a 400 LPH Walbro pump. It fits precisely to the Impala B body chassis, matching factory crossmembers and sheetmetal contours to eliminate trimming or filler modifications. The galvanized steel construction and protective powder coat ensure long service life, while the included hardware set streamlines installation for LS engine swaps.
400 LPH Walbro Pump Performance
The included 400 LPH Walbro pump delivers steady fuel pressure under extreme demand, supporting engines up to 750 horsepower with ease. Mounted directly in the fuel column, it minimizes cavitation and prevents vapor lock during hard acceleration or steep inclines. Consistent fuel flow enhances throttle response and ensures reliable combustion across a wide range of driving conditions. By positioning the pump inside the tank, the design also reduces noise and heat build up, extending the service life of the module.
Precision Tank Geometry for Impala B Body Fitment
This EFI fuel tank features a depth increase of three quarters of an inch and a length reduction of five inches compared to stock, creating extra clearance around crossmembers without compromising capacity. Its contours follow the factory sheetmetal lines of 1969 and 1970 Impala B Body frames, so installers can bolt it in place with no trimming or filler modifications. The result is a seamless underbody integration that preserves chassis geometry and maintains ground clearance. Attention to these dimensions ensures a perfect match for LS engine swap configurations.
Robust Steel Structure with Protective Powder Coat
Constructed from galvanized steel, the tank resists corrosion and stands up to road grit, salt, and moisture for long service life. A durable powder coat finish adds a second barrier against chemicals and abrasion, keeping the exterior appearance clean and damage free. Together, these treatments reduce maintenance needs and guard against leaks or rust even in harsh environments. This steel and coating combination offers a reliable solution for high volume fuel delivery setups.
Complete Kit Components Simplify Installation
This all inclusive kit supplies every component needed for a straightforward installation: the fuel pump module, sending unit, tank straps, filler neck, vent filter, gaskets, and mounting hardware. Each part is engineered to match the tank's dimensions and flow requirements, eliminating fitment issues and extra parts sourcing. By covering both fuel delivery and installation hardware, the package accelerates project timelines and reduces the risk of mismatched components. Installers gain confidence that every connection meets the kit's intended design specifications.
