Understanding the Craftsman Rototiller Gas Tank
What Is a Craftsman Rototiller Gas Tank?
The gas tank in a Craftsman rototiller is a container designed to hold gasoline safely and deliver it to the engine. Its primary purpose is to supply a steady flow of fuel that powers the engine's combustion process. The design typically includes a cap for refilling, a fuel line that transfers the fuel to the carburetor, and sometimes vents to allow for proper fuel flow and prevent pressure buildup.
Materials and Construction
Most Craftsman rototiller gas tanks are made from durable plastics like high-density polyethylene (HDPE) or metal, depending on the model and age of the equipment. Plastic tanks are lightweight, resistant to corrosion, and easy to manufacture, while metal tanks tend to be more durable but heavier and prone to rust if not properly maintained.
Common Issues with Gas Tanks
Over time, gas tanks can develop various problems, including:
- Cracks or leaks due to impacts or aging
- Clogged fuel lines or vents
- Corrosion or rust (especially in metal tanks)
- Contaminated fuel or debris inside the tank
- Difficulty in refilling due to damaged caps or seals
Understanding these issues can help you diagnose and address problems promptly, ensuring your Craftsman rototiller remains in optimal condition.

Choosing the Right Gas Tank for Your Craftsman Rototiller
OEM vs. Aftermarket Tanks
When replacing a gas tank, you have the option to choose between Original Equipment Manufacturer (OEM) parts and aftermarket alternatives. OEM tanks are manufactured specifically for Craftsman models, ensuring perfect fit and compatibility. Aftermarket tanks are usually less expensive and readily available but may vary in quality.
Pros of OEM Gas Tanks:
- Guaranteed compatibility
- Built to original specifications
- Usually come with warranty
Pros of Aftermarket Gas Tanks:
- Cost-effective
- Widely available
- May offer additional features or capacities
Compatibility Considerations
Before purchasing a replacement gas tank, verify:
- Model number compatibility
- Capacity requirements
- Mounting and connection points
- Material preferences (plastic vs. metal)
Consult your Craftsman rototiller’s manual or contact the manufacturer for precise specifications.

Frequently Asked Questions
How do I properly fill the gas tank on my Craftsman rototiller?
To properly fill the gas tank, ensure the engine is off and cooled down. Use a clean funnel to pour fresh, unleaded gasoline into the tank, avoiding overfilling. Wipe any spills and securely tighten the cap before starting.
What are common issues with the Craftsman rototiller gas tank?
Common issues include fuel leaks due to a damaged or loose cap, clogged venting causing difficulty starting, and sediment buildup in the tank leading to poor performance. Regular maintenance and inspection can help prevent these problems.
How can I prevent fuel leaks from the Craftsman rototiller gas tank?
Ensure the gas cap is tightly secured and in good condition. Replace any cracked or worn caps. Avoid overfilling the tank and always use the recommended fuel type to prevent pressure buildup and leaks.
What should I do if my Craftsman rototiller's gas tank is empty or runs out during use?
Refill the tank with fresh gasoline, ensuring the engine is off and cooled. Check for any leaks or blockages if refilling doesn't resolve issues. Regularly check fuel levels before use to prevent running out mid-operation.
How often should I inspect the gas tank on my Craftsman rototiller?
