LS EFI Fuel Tank Kit 255LPH Pump for 1973-1987 GM C10/C15 K10/K15 Trucks 8ft Bed
If you are tackling an LS swap into a classic C10 or K15 eight foot bed truck, securing a steady fuel supply is essential and this 1973 to 1987 GM Truck EFI Fuel Tank Kit with 255 LPH pump meets that demand. Built in a steel shell molded to match factory tabs on C10, C15, K10 and K15 frames it installs without cutting or welding and preserves original frame geometry. Its internal baffling channels fuel toward the pickup during cornering or hard throttle to prevent starvation under load. Housing the Walbro pump inside the tank also uses surrounding fuel to moderate operating temperature while the included sending unit and mounting hardware deliver a plug and play solution for EFI systems up to 550 horsepower.
Factory Matched Steel Tank for Frame Integrity
The tank shell is stamped and formed to lock into the factory mounting tabs on 1973 through 1987 GM C10, C15, K10 and K15 frames without any cutting or welding. By mirroring the original chassis contours, this design preserves ride height and maintains the truck's structural rigidity under load. Installers save time and avoid custom bracket fabrication since the tank drops into place and aligns precisely. The accurate fitment also minimizes stress on the retaining straps, reducing the risk of rattles or movement over rough roads. Ultimately, maintaining the stock frame interface ensures the truck handles as its designers intended.
Immersed 255 LPH Pump for Consistent Flow and Cool Operation
Housing the 255 LPH Walbro pump entirely inside the fuel chamber allows the surrounding gasoline to act as a natural coolant and heat sink. This immersion setup keeps the pump running at stable temperature levels even during extended high-demand driving or sustained high rpm bursts. Consistent thermal control prevents heat-related wear, extending service life and avoiding sudden drops in flow rate. The result is a reliable fuel supply able to support LS engines up to 550 horsepower without hesitation. Precise pump output further ensures that injectors receive the correct pressure for optimal combustion.
Baffled Interior Network to Prevent Fuel Starvation
Strategically placed internal partitions create multiple compartments that confine fuel around the pickup during hard acceleration, cornering or braking. Each baffle opening is calibrated to balance rapid refill when fuel levels are low with the need to limit slosh under extreme g-forces. This containment system keeps the pump intake submerged at all times, eliminating vapor pockets and maintaining uninterrupted fuel pressure. As a result, drivers experience crisp throttle response even when pushing the truck through demanding maneuvers. This level of fluid management is essential when adapting an LS swap to the dynamics of a vintage GM pickup.
Complete American Made Kit Reducing Assembly Time
Every component in this kit is manufactured in the United States to resist modern fuel blends and resist corrosion over years of service. Alongside the 255 LPH pump, you receive a calibrated sending unit, filler neck, vent filter, gaskets, tank straps and all necessary hardware. Each part is engineered for precision fit against GM eight foot bed truck frame tabs and fuel system plumbing. With every piece included, builders can perform a plug and play installation that cuts down on sourcing delays and ensures leak-free operation. Rigorous quality checks confirm dimensional accuracy and functional reliability before the kit ships.
You can trust MuscleRods for precision engineered fit and lasting reliability. To upgrade to a larger capacity fuel pump Kit at 400 LPH see our 1973-1987 GM Truck EFI Fuel Tank Kit - 400 LPH Pump - 8' bed.
