LS EFI Fuel Tank for 1973-1987 C10/C15 K10/K15 GM Trucks
When planning an LS powertrain conversion in a classic 1973-1987 GM six foot bed truck, reliable fuel delivery starts with the 1973-1987 GM Truck EFI Fuel Tank Kit, featuring a 255 LPH Walbro pump rated to support up to 550 horsepower. Since it drops into C10, C15, K10 and K15 chassis without tunnel alterations, this assembly works seamlessly with 4L60E or 4L80E transmissions while maintaining consistent fuel pressure. Installation is simplified by precise tank straps, factory style vent filters and high quality gaskets that secure a proper fit and lasting dependability.
Drop In Fitment for 1973 to 1987 GM Six Foot Bed Trucks
This EFI fuel tank kit is crafted to follow 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 matching factory mounting points, the precise tank straps and hardware secure the assembly in the same position as the stock tank, preserving ride height and avoiding clearance issues. This approach not only saves hours of custom work but also ensures the integrity of the frame and driveshaft alignment remain factory correct.
High Capacity 255 LPH Walbro Pump for Engines Up to 550 HP
At its heart resides a 255 liter per hour Walbro in-tank pump engineered to handle the demands of engines producing up to 550 horsepower. Maintaining consistent fuel pressure under heavy acceleration prevents lean conditions that can damage high output powerplants. By locating the pump inside the tank, this design reduces turbulence and heat soak, promoting longer pump life and steady flow even in spirited cornering or steep inclines.
Seamless LS Swap and Transmission Compatibility
Designed specifically for modern LS engine conversions, this kit accommodates common powertrain pairings with both 4L60E and 4L80E transmissions without requiring tunnel modifications. That means you can install your chosen GM small block crate engine and transmission combo with minimal fabrication, streamlining the swap process. The result is a reliable drop-in solution that preserves firewall alignment and driveshaft angles, essential for smooth drivability and reduced wear.
Comprehensive Kit with OEM Style Components
Every installation component arrives ready for assembly, including the fuel pump module, sending unit, filler neck, vent filter and high-quality gaskets. By using factory style vent filters and precision-cut gaskets, the kit maintains proper tank venting and prevents leaks under pressure. All tank straps, hardware and seals are manufactured in the USA to exacting standards, ensuring a tight fit and lasting durability in daily driving or restored show vehicles.
