1967-1972 Chevy Truck Frame Mount LS Gas Tank with 255 LPH Pump
Swapping an LS engine into a 1967 to 1972 Chevy truck often leaves installers hunting for a tank that fits the original frame rails and keeps the fuel system fed under load. Crafted to tuck neatly beneath the rear frame members, this gas tank pairs with a bed-mounted fill neck that lets you refuel without crawling under the chassis. It features an 18 gallon capacity and a 255 LPH pump capable of supporting engines up to 550 HP while EFI style baffling prevents slosh during braking and cornering. Every element combines to deliver precise fuel level readings through the original gauge cluster and maintain consistent flow on demanding drives.
Frame-Mount Precision for 1967 to 1972 Chevy Trucks
The custom frame-mount design for 1967 to 1972 Chevy trucks precisely targets the original rear rails, preserving factory geometry and ground clearance. This tailored shape aligns with existing bolt patterns so installation avoids bracket modification and maintains proper exhaust and brake line clearance. Even under a full 18 gallon load, direct attachment to the chassis ensures the tank remains secure on rugged roads. The compact footprint of 32¼ by 20½ by 9¾ inches fits neatly beneath the bed without sacrificing cabin or cargo space.
Convenient Bed Fill Refill System
The bed fill neck positions the fuel inlet flush with the bed floor for easy access and spill free operation. Standard pump nozzles slide in smoothly, making refueling quick at the pump and reducing downtime on long hauls. Clear mounting points help prevent interference with bed liners or crossmembers and simplify the routing of vent and filler hoses. This arrangement streamlines the process for day to day use or extended road trips.
EFI Style Baffling for Constant Fuel Flow
Internal baffling follows EFI style principles to keep fuel slosh under control when braking or cornering. Strategically placed partitions form separate chambers that trap liquid around the pump inlet and prevent air pockets. This design not only reduces noise but also ensures the pump remains submerged during sudden maneuvers, eliminating starvation under high demand. Drivers benefit from steady engine performance even in spirited driving conditions.
Integrated Walbro 255 Pump with Precision Sending Unit
A high volume 255 LPH Walbro pump supports powerplants up to 550 horsepower, delivering ample capacity for spirited driving or towing. The 0 to 90 ohm sender ties directly into the original gauge cluster, giving accurate fuel level readings without aftermarket adapters. Constructed from corrosion resistant steel, the assembly resists harsh road conditions and fuel blends. Combined with quality fuel lines and filters, it provides consistent pressure and flow for reliable operation mile after mile.
Engineered for precise fit and consistent flow in your LS truck swap.
