Frame Mount LS Swap Fuel Tank with 400 LPH Pump for 1963-1966 Chevy Trucks
When fitting an LS engine into a 1963 to 1966 Chevy pickup the last thing you want is fuel starvation. This frame mounted gas tank with a 400 LPH pump delivers the consistent volume needed during hard acceleration and long sweeps. Featuring internal baffles it prevents fuel from sloshing away from the pickup inlet when cornering or braking. A convenient bed fill neck and 0 to 30 ohm sending unit match factory gauge readings while the EFI ready design makes it a straightforward swap solution.
Internally Baffled Design to Prevent Fuel Starvation
The tank's internal baffles create separate zones that keep fuel positioned around the pickup inlet during hard cornering and sudden braking. By reducing fluid movement inside the tank, these barriers ensure the Walbro pump remains fully submerged and maintains steady pressure. This design minimizes the risk of cavitation and momentary fuel loss, which is critical when accelerating out of tight turns or driving up steep grades. As a result, drivers experience uninterrupted power delivery and more predictable throttle response under demanding conditions.
Integrated Walbro 400 LPH Pump Supporting Up To 750 HP
Mounted directly inside the tank, the high-volume Walbro pump delivers up to 400 liters per hour, supplying enough fuel for engines producing up to 750 horsepower. Its in-tank location benefits from constant cooling by the surrounding gasoline, extending service life and reducing noise transmission into the cab. This configuration also simplifies plumbing by eliminating external feed lines, cutting installation time and potential leak points. The pump's robust design makes it a reliable choice for both street rods and track applications.
EFI Ready Configuration with 0 to 30 Ohm Sending Unit
Factory-style wiring provisions and fuel line fittings allow for seamless integration with modern electronic fuel injection systems. The included 0 to 30 ohm sending unit matches original Chevy gauge circuits, so no custom calibration is needed for accurate level readings. This precision sender ensures the driver's dash gauge reflects true tank volume, avoiding guesswork during extended drives. Combined with the bed fill neck, refueling and monitoring become straightforward tasks that align with factory ergonomics.
Generous 18 Gallon Capacity for Extended Driving Range
With room for 18 gallons of fuel, the tank significantly reduces the frequency of stops on long highway runs or spirited road trips. Its frame-mount design maintains factory ride height and ground clearance while fitting neatly between the rails of 1963-1966 Chevy pickups. The extra capacity also adds weight low and central in the chassis, improving handling stability. For enthusiasts who demand both authenticity and endurance, this fuel tank offers an ideal balance of classic styling and modern convenience.
