When swapping an LS engine into a Chevy Blazer, Suburban or GMC Jimmy from 1973 through 1991, consistent fuel delivery can make or break your build and this Fuel Tank Kit rises to the challenge. Each kit arrives complete with a tank mounted 255 LPH pump, sending unit, vent filter and all mounting hardware for direct installation. With support for engines up to 550 hp, the assembly maintains steady pressure to prevent lean conditions during sudden throttle openings and supports precise EFI control from idle through peak rpm. That combination of tailored fit and reliable delivery keeps your fuel system dependable on daily drives and spirited runs alike.
Optimized Pump Performance for LS Engine Demands
The 255 LPH Walbro pump at the core of this kit delivers precise fuel volume to support LS engines up to 550 hp, preventing lean conditions during rapid throttle changes. Its design maintains consistent pressure across the entire rpm range, which is critical for electronic fuel injection systems that rely on steady supply for efficient combustion. By matching pump capacity to the high output of modern LS setups, drivers experience smooth power delivery from idle through peak load. Careful calibration of flow rate and pressure ensures reliable fuel delivery on both street cruises and spirited acceleration.
Custom Fitment for 1973 through 1991 Blazer, Suburban and Jimmy
Every component in this fuel tank kit is shaped to align perfectly with the frame rails and mounting bosses of 1973 through 1991 Chevy Blazer, Suburban and GMC Jimmy models, eliminating the need for cutting or fabrication. The tank straps, gaskets and filler neck hardware bolt directly to factory points, reducing install time and minimizing the risk of leaks. The sending unit is factory calibrated to maintain accurate fuel level readings in the stock gauge cluster. This tailored fitment streamlines installation and preserves the vehicle's original underbody geometry.
Integrated Module Simplifying EFI Conversion
This all-in-one package brings together an in-tank pump module, sending unit, vent filter and mounting hardware to cover every aspect of a modern EFI fuel system. The vent filter prevents debris and vapor lock, while OE-style straps hold the assembly firmly against vibration. Included gaskets and seals ensure a leak-free connection between the tank, neck and module, providing peace of mind during daily use. Having all parts engineered as a cohesive system removes guesswork and guarantees reliable operation in any driving condition.
