Stens replacement fuel cap with gauge for Cub Cadet 2" ID — 10.625" length, E10 compatible

Stens 125-280 is a replacement fuel cap with an integrated gauge designed to fit select Cub Cadet models and provide a secure, visible fuel seal.

This fuel cap is an OEM-sourced replacement built to the original dimensions for Cub Cadet machines from the 1980s. It measures 10 5/8" overall length with a 2" inside diameter and includes a fuel-level gauge so you can check tank contents at a glance. Note that this cap is not compatible with fuels containing more than 10% ethanol.

Will this fuel cap fit my Cub Cadet mower or tractor?

If you have a Cub Cadet manufactured between 1980 and 1989 that originally used part numbers 751-0226A or 951-0226A, this Stens cap is intended as a direct replacement. Always confirm the part number or measure the tank opening before ordering.

• Replaces OEM numbers: 751-0226A and 951-0226A
• Compatible with Cub Cadet models from 1980–1989
• Measure tank opening: 2" inside diameter required
• Overall length: 10 5/8" to match original fit

How does the integrated gauge help me in the field?

The built-in gauge gives a quick visual check of fuel level without removing the cap, saving time and reducing fuel spillage. The gauge is simple and mechanical, designed for basic level indication rather than precision metering.

• Quick visual fuel checks reduce stops for inspections
• Minimizes fuel spillage and exposure during checks
• Mechanical gauge suitable for routine equipment use
• Easy to read without special tools or electronics

What fuel types can I use with this cap?

This cap is compatible with conventional gasoline blends containing up to 10% ethanol (E10). It is not recommended for use with higher ethanol concentrations or alternative fuels, which can degrade seals and internal components.

• Safe for gasoline mixes up to 10% ethanol (E10)
• Avoid E15, E85, and other high-ethanol blends
• Not designed for diesel, kerosene, or specialty fuels
• Use fresh, approved fuel to protect cap materials

How do I confirm fit and install the replacement cap?

Check the original cap for the Cub Cadet part number or measure the tank throat diameter (2" ID) and overall clearance for a 10 5/8" length. Installation is straightforward: remove the old cap, align the replacement, and press or screw it into place depending on the tank's mounting style.

• Verify OEM numbers 751-0226A or 951-0226A when possible
• Measure tank opening: 2" inside diameter required
• Confirm there is room for a 10 5/8" cap length
• Install by aligning and seating the cap securely

Who is this for? This Stens 125-280 fuel cap is for owners and technicians of classic Cub Cadet lawn and garden equipment (model years 1980–1989) who need a reliable, OEM-dimension replacement with a fuel-level gauge. It's ideal for people restoring older machines, maintaining fleets of vintage equipment, or anyone who prefers a visible gauge and correct mechanical fit. Avoid this cap if you rely on high-ethanol fuels or need a modern vapor-tight venting system.
