The Tanks, Inc. 48DP-A is a 15-gallon replacement fuel tank designed for 1941-1948 Dodge and Plymouth passenger cars. Manufactured from corrosion-resistant aluminized steel, this tank combines classic Mopar vehicle compatibility with modern construction, internal baffling, and provisions for optional in-tank electric fuel pumps.

Whether you're restoring a vintage Dodge or Plymouth, replacing a deteriorated original fuel tank, or building a custom street rod with modern electronic fuel injection, the 48DP-A provides a practical replacement fuel tank with quality construction and versatile fuel system options.

Vehicle Applications

• 1941-1948 Dodge passenger cars
• 1941-1948 Plymouth passenger cars
• Compatible coupes, sedans, convertibles, and other passenger car body styles

Fitment should be confirmed against the vehicle's original fuel tank, mounting arrangement, filler neck configuration, and available clearance before ordering. Custom chassis, modified bodywork, and previous fuel system alterations may affect installation requirements.

Aluminized Steel Construction

The 48DP-A is manufactured from aluminized steel to provide corrosion resistance compared with untreated steel fuel tanks.

Its electronically seam-welded construction and manufacturer leak testing help ensure dependable fuel containment and operation.

The tank incorporates internal baffling to reduce excessive fuel movement during acceleration, braking, and cornering. This feature provides an advantage over basic unbaffled replacement tanks.

Universal mounting straps are included to assist with installation. Additional installation hardware or modifications may be necessary depending on the vehicle's condition and mounting arrangement.

Fuel Pickup & Sending Unit Compatibility

The 48DP-A includes a built-in 3/8-inch NPT internal fuel pickup tube for conventional fuel delivery applications.

The tank accepts compatible aftermarket fuel-level sending units. The appropriate electrical resistance range must be matched to the vehicle's fuel gauge.

Original-style Dodge and Plymouth gauges commonly use approximately 73 ohms empty and 10 ohms full. Aftermarket gauges may require different sender resistance ranges.

When using a tubular or reed-switch fuel-level sending unit, Tanks, Inc. specifies an 8-inch sender length for this tank.

Important: The fuel-level sending unit is sold separately. Verify the sender mounting pattern, electrical resistance range, and tank compatibility before installation.

Traditional Restoration & Carbureted Applications

The 48DP-A can be used in properly configured traditional carbureted fuel systems, making it suitable for restorations that retain the original engine and fuel delivery arrangement.

Its internal fuel pickup tube, bolt-on filler neck, and original-style vehicle compatibility provide a practical starting point for replacing an aging, damaged, or corroded fuel tank.

During installation, inspect the fuel lines, fittings, fuel filters, connecting hose, mounting components, and tank venting system. Any damaged or incompatible parts should be replaced.

Fuel delivery components must be selected to match the engine's requirements and intended vehicle use.

Electronic Fuel Injection Conversion

The 48DP-A can also accommodate a compatible Tanks, Inc. GPA-Series in-tank electric fuel pump module for electronic fuel injection applications.

The tank is fully baffled, and the manufacturer specifically identifies it as compatible with optional GPA-Series fuel pumps.

Important installation requirement: When installing a GPA-Series electric fuel pump, Tanks, Inc. requires a 3/8-inch NPT pipe plug to close off the original internal fuel pickup tube.

The electric fuel pump is not included with the fuel tank and must be purchased separately.

EFI conversions require additional components, including appropriate fuel pressure regulation, filtration, electrical wiring and controls, fuel supply and return plumbing, and a properly designed tank venting system.

Potential applications include custom Dodge and Plymouth restomods using LS, LT, Ford Coyote, or other modern fuel-injected engines. The fuel pump must be selected according to the engine's actual fuel pressure, flow, and electrical control requirements.

Not every GPA-Series pump has the same flow rating or electrical control characteristics. Confirm the selected pump's compatibility with the engine management system before ordering.

Filler Neck & Mounting Considerations

The 48DP-A uses a bolt-on filler neck and a 2-1/4-inch inside-diameter angled fuel-resistant connecting hose.

The tank includes universal mounting straps, but proper installation requires confirming the original mounting locations, chassis clearance, filler neck alignment, exhaust clearance, and fuel line routing.

Additional clamps, fasteners, fittings, and other installation components may be required depending on the vehicle and the condition of its original hardware.

Vehicles equipped with aftermarket chassis, modified suspension systems, relocated exhaust, or custom bodywork should be checked for mounting and ground clearance before installation.
