Best Fuel Tank Options for a 1965–1970 Ford Mustang: Rick’s Tanks, Aeromotive, and More

Owning a classic Ford Mustang is about preserving an iconic piece of American automotive history while making it perform the way you want. Whether you're restoring a 1965 Mustang fastback, building a street-driven 1967 coupe, or upgrading a powerful 1969–1970 Mustang with modern fuel injection, choosing the right fuel tank is an important part of the project.

A quality 1965–1970 Mustang fuel tank can help support reliable fuel delivery, improve compatibility with your engine setup, and make future performance upgrades easier. Today's options range from traditional replacement gas tanks to custom stainless steel tanks and advanced in-tank fuel delivery systems from manufacturers such as Rick's Tanks and Aeromotive.

At Stang-Aholics, Mustang enthusiasts can explore a variety of fuel tank options designed for classic Mustang restorations, restomods, and performance builds. The key is finding a tank that matches your Mustang's model year, fuel system, horsepower goals, and intended use.

Why Upgrade Your Classic Mustang Fuel Tank?

The original fuel tank in a vintage Mustang may have served faithfully for decades, but age, corrosion, contamination, and changes to the engine can make replacement a smart investment.

A new fuel tank may be worth considering if you're experiencing fuel delivery problems, restoring a car that has been sitting for years, or converting an original carbureted engine to electronic fuel injection (EFI).

Common reasons to upgrade include:

• Improved fuel delivery: Modern fuel systems may require a tank and pump combination designed for consistent fuel supply.
• EFI conversion compatibility: Electronic fuel injection often requires a suitable high-pressure electric pump, return or returnless plumbing as specified by the system, and appropriate tank baffling.
• Increased performance potential: Engine modifications can increase fuel demand, making pump capacity and the complete fuel system more important.
• Restoration and reliability: Replacing a deteriorated tank can help eliminate problems caused by internal rust and debris.
• Custom build flexibility: Restomod and pro-touring projects may benefit from larger-capacity or fabricated stainless steel tanks.

The right choice depends on more than tank capacity. Pump flow, fuel type, sender compatibility, tank design, installation requirements, and the rest of the fuel system all matter.

Rick's Tanks for 1965–1970 Mustangs

For enthusiasts building a distinctive classic Mustang, Rick's Tanks is a name worth investigating when comparing custom fuel tank solutions.

Rick's Tanks is known for custom and performance-oriented fuel tank applications. Depending on the specific product and vehicle configuration, a custom tank may offer options for fabrication, fuel system integration, and adapting the fuel storage system to a modified build.

A Rick's tank may be worth considering if your 1965–1970 Mustang is being transformed into a restomod, a high-performance street car, or a custom project that requires something beyond a conventional factory-style replacement.

What to Consider Before Choosing a Rick's Tank

Before ordering, verify the exact tank application for your Mustang year and body style. The 1965–1966, 1967–1968, and 1969–1970 Mustangs do not all share identical tank configurations.

Review these details with the specific product listing or manufacturer:

• Vehicle year and body-style fitment
• Tank material, construction, and fuel capacity
• Compatibility with carbureted or EFI fuel systems
• In-tank pump provisions and baffling, if applicable
• Fuel sender and gauge compatibility
• Filler neck, venting, mounting, and plumbing requirements

For a custom build, it is especially important to confirm whether the tank includes a fuel pump or requires separately selected fuel delivery components. Do not assume every custom tank has the same features.

Best for: Mustang owners evaluating custom fuel storage solutions for a modified restoration, restomod, or performance project.

Aeromotive Fuel Tanks for 1965–1970 Mustangs

When upgrading a classic Mustang for modern fuel injection or increased engine output, Aeromotive is another important option to consider.

Aeromotive specializes in performance fuel delivery systems, including fuel pumps and integrated tank assemblies. Its Mustang-specific Gen II Stealth fuel tanks are designed to combine fuel storage with an in-tank pump arrangement for compatible applications.

Stang-Aholics lists Aeromotive Gen II Stealth fuel tank options for 1964–1968 and 1969–1970 Mustangs, with different pump-flow configurations available depending on the application.

Aeromotive Gen II Stealth Tanks: 1965–1968 Mustang

For 1965, 1966, 1967, and 1968 Mustangs, the Aeromotive Gen II Stealth range is worth exploring when planning an EFI conversion or upgrading the fuel delivery system.

Depending on the selected configuration, the system incorporates an in-tank electric pump and fuel management features designed to help maintain a consistent fuel supply.

When comparing options, look at the specified pump flow, fuel pressure requirements, sender compatibility, and whether the system is suitable for your particular engine management setup.

A properly matched in-tank pump can also reduce the need for some of the external plumbing and hardware associated with an external-pump installation.

Aeromotive Gen II Stealth Tanks: 1969–1970 Mustang

The 1969 and 1970 Mustangs have their own Aeromotive Gen II Stealth tank applications, making it important to choose the correct version rather than relying on a generic classic Mustang listing.

Stang-Aholics lists two notable configurations:

• 200 LPH version: A lower-flow option to evaluate for compatible street and EFI applications.
• 340 LPH version: A higher-flow option to evaluate for engines with greater fuel delivery demands.

LPH means liters per hour, a measure of fuel pump flow. The actual horsepower supported depends on fuel type, operating pressure, pump performance at that pressure, and the engine's fuel consumption.

Aeromotive's Gen II Stealth design includes an integrated in-tank pump arrangement and baffling intended to help maintain fuel supply during driving. Its product information also describes factory-location outlet, return, and electrical connections for compatible installations.

Always confirm the specific product's included components and fitment before purchasing.

Best for: Classic Mustang owners who want an integrated fuel tank and pump solution for a compatible EFI conversion or performance-oriented fuel system.

Comparing Fuel Tank Options for Your Mustang

There is no single best fuel tank for every classic Mustang. The right choice depends on your budget, restoration goals, engine setup, and plans for future modifications.

1. Stock-Style Replacement Fuel Tanks

A stock-style replacement tank is often a practical choice for a traditional restoration or a mostly original Mustang.

These tanks prioritize factory-style fitment and familiar installation requirements. They may be particularly suitable for owners retaining a carburetor and a conventional mechanical fuel pump, provided the replacement matches the original application.

Advantages:

• Appropriate for many factory-style restorations
• Familiar installation and component layout
• Often a straightforward replacement approach

Considerations: A standard replacement tank does not automatically provide the high-pressure pump, baffling, or plumbing needed for an EFI conversion.

2. EFI-Ready Fuel Tanks

EFI-ready tanks are designed for builds that use electronic fuel injection. Depending on the product, they may include internal baffling, a fuel tray, an electric pump, and a compatible sending unit.

Stang-Aholics also lists EFI-ready replacement tanks for 1964–1968 Mustangs and 1969–1970 Mustangs, with different pump options available for selected applications.

These products can simplify an EFI conversion by integrating several fuel delivery components into one assembly.

Advantages:

• Designed with EFI conversion needs in mind
• Potentially fewer separate components to source
• Internal fuel management features on applicable models

Considerations: Check fuel pressure, pump capacity, electrical requirements, sender resistance, and compatibility with your EFI controller.

3. Custom and Fabricated Stainless Steel Tanks

A fabricated stainless steel tank may appeal to owners who prioritize custom construction, a distinctive build, or additional fuel capacity.

Stang-Aholics lists fabricated 22-gallon stainless steel fuel tank options for 1967–1968 and 1969–1970 Mustangs. These are alternatives to investigate when comparing custom fabrication with an integrated EFI tank.

• Integrated in-tank pump design
• Available pump-flow choices for supported applications
• Features intended to help manage fuel supply during driving

Considerations: Select the correct model year and pump configuration, then ensure the pump can meet your engine's actual fuel requirements.

5. Rick's Tanks Custom Solutions

For a build with specialized requirements, investigate the Rick's Tanks products available for your vehicle and intended fuel system.

Custom fuel tanks can be useful when a project calls for a particular configuration or requires more planning than a conventional stock-style replacement. However, product features vary, so confirm the specifications of the exact tank rather than assuming all Rick's applications offer the same construction or fuel system provisions.

Advantages:

• Worth evaluating for custom and modified builds
• May offer solutions for applications that differ from factory configurations
• Can be considered alongside fabricated and integrated EFI tanks

Considerations: Confirm the exact 1965–1970 fitment, included hardware, tank dimensions, fuel capacity, and EFI compatibility with the manufacturer or seller.

How to Choose the Right Fuel Tank for Your Build

Before ordering a new Mustang gas tank, answer five important questions.

1. What year is your Mustang?

Start with exact year fitment. A tank for a 1965–1966 Mustang should not be assumed to fit a 1967–1968 or 1969–1970 model without explicit manufacturer confirmation.

2. Are you running a carburetor or EFI?

A carbureted engine typically uses a different fuel delivery arrangement from a modern EFI engine. An EFI conversion may require an electric pump capable of maintaining the specified pressure and flow, along with compatible fuel lines, filtration, regulation, wiring, and venting.

3. How much fuel flow does your engine require?

Choose the pump based on the engine's expected horsepower, fuel type, and operating pressure. A higher LPH rating is not automatically better if the pump is mismatched to the application.

A properly designed fuel system should provide sufficient flow at the pressure the engine requires, with an appropriate safety margin.

4. Will you drive on the street or at the track?

A daily driver, weekend cruiser, pro-touring car, and dedicated drag car may have very different fuel delivery requirements.

Internal baffling and fuel tray design can be particularly important when cornering, accelerating hard, or braking aggressively, because fuel movement inside the tank can temporarily uncover the pump pickup.

5. What else must be replaced?

A new tank may be only one part of the job. Inspect the filler connection, hoses, fuel lines, clamps, venting, sender, pump wiring, filter, and mounting hardware. Replace worn or incompatible components as necessary.

For EFI conversions, confirm that the entire system is rated for the intended fuel and operating pressure.

Frequently Asked Questions About 1965–1970 Mustang Fuel Tanks

What is the best fuel tank for a 1965–1970 Mustang?

The best tank depends on the car's model year, engine, fuel system, and intended use. A stock-style tank may suit an original restoration, while an EFI-ready or Aeromotive Stealth assembly may be a better fit for a compatible fuel injection conversion. Rick's Tanks is another option to investigate for custom projects.

Can I install an EFI fuel tank in an originally carbureted Mustang?

Yes, an EFI tank can be part of a carburetor-to-EFI conversion when the tank, pump, fuel lines, pressure regulation, wiring, and engine management system are compatible. Check the complete system requirements before installation.

What is the difference between a 200 LPH and 340 LPH Aeromotive tank?

The primary distinction is the rated flow of the included fuel pump. A 340 LPH pump offers a higher nominal flow rating than a 200 LPH pump, but actual delivery depends on operating pressure and fuel type. Choose based on the engine's real fuel requirements rather than pump size alone.

Are 1965–1968 and 1969–1970 Mustang fuel tanks interchangeable?

Do not assume they are interchangeable. Tank shape, capacity, mounting, filler arrangements, and fuel system provisions can differ. Always use the manufacturer's stated vehicle application.

Should I choose a stock-style tank or a custom tank?

A stock-style tank is often appropriate for a traditional restoration. A custom or fabricated tank may be worth considering for a restomod, modified fuel system, or build with specialized requirements. Compare the exact specifications and installation needs before making a decision.
