255 LPH LS Fuel Tank for 73-87 C/K Trucks

For effortless LS engine swaps in 1973 to 1987 GM trucks with six foot beds, this EFI fuel tank kit integrates a 255 LPH in tank Walbro pump to maintain steady flow for engines up to 550 hp. Compatible with 4L60E and 4L80E transmissions for a direct install without altering the floor pan, and precision fit components for classic C/K trucks accelerate your build. Made in the USA to exacting standards, it sharpens throttle response, boosts drivability and delivers durable performance.

LS Fuel Tank Kit for 1973-1987 C10/C15 and K10/K15 Chevy and GMC Trucks

If you are dropping an LS small block into a classic C10 or K15 chassis, the 1973 to 1987 GM Truck EFI Fuel Tank Kit is engineered to ensure consistent pressure and flow under all driving conditions. Its 255 liter per hour in tank Walbro pump supports engines up to 550 horsepower while fitting directly into six foot beds without any floor pan cuts or tunnel alterations. Precision tank straps, factory style vent filters and high quality gaskets secure a leak free seal and speed up installations. Complete compatibility with both 4L60E and 4L80E transmissions preserves original driveshaft angles for dependable performance.

Direct Drop In Fitment for 1973 to 1987 GM Six Foot Bed Trucks

The fuel tank kit is shaped to match the original underbody contours of C10, C15, K10 and K15 chassis, allowing it to slide into a six foot bed without any cutting or tunnel alterations. By aligning with factory mounting points, the precision tank straps and hardware secure the assembly exactly where the stock tank sat, preserving ride height and avoiding clearance issues. This design not only slashes installation time but also maintains the integrity of the frame and driveshaft angle for reliable operation. Technicians benefit from a straightforward bolting procedure that keeps welding and fabrication work to a minimum.

Precision Fuel Delivery with 255 LPH Walbro Pump

At the core of the system lies a 255 liter per hour Walbro pump, rated to support engines up to 550 horsepower, that resides inside the tank to reduce turbulence and limit heat soak. Maintaining stable pressure under heavy acceleration prevents lean conditions that could harm high output small block powerplants. The submerged location not only extends pump life but also ensures uniform flow during spirited cornering or steep climbs. Consistent fuel supply is critical for tuned LS engines and this arrangement delivers smooth, uninterrupted performance in all driving scenarios.

Complete OEM Style Kit for Leak Free Operation

This comprehensive kit includes the pump module, sending unit, filler neck, vent filter and precision cut gaskets, plus straps and hardware that replicate factory parts. By combining correctly sized gaskets with a filter modeled on original vent designs, the assembly prevents pressure build up and keeps contaminants out. All seals and mounting components are made in the USA to stringent standards, ensuring a tight fit and lasting durability. The result is a fuel delivery system that performs like an original part while supporting modern EFI upgrades.

Smoother Throttle Response from EFI Upgrade

Switching from carbureted fuel delivery to electronic injection brings more consistent atomization and rapid adjustment to changing load conditions. The high capacity pump and refined tank design feed the fuel rail with steady pressure, eliminating hesitation under sudden throttle inputs. Drivers notice improved throttle response and crisper acceleration as the system maintains ideal air fuel ratios at all times. This advanced setup enhances overall drivability, making the classic GM truck feel more responsive and reliable in everyday use.

Count on consistent operation in your classic GM truck. For a Larger capacity fuel pump Kit at 400 LPH see our 1973-1987 GM Truck EFI Fuel Tank Kit - 400 LPH Pump - 6' bed.
