CLLOMAGY Oil Tank Gauge for 275/330 gal Vertical Tanks — 1-1/2" or 2" NPT, Steel Body & UV Cap

CLLOMAGY oil tank gauge is a direct-fit replacement level gauge for 275 and 330 gallon vertical heating oil tanks compatible with Scully Scul-Tel and Intelli-Tank systems.

This replacement fuel oil tank gauge restores accurate level readings so you can stop guessing how much heating oil remains. Built for the common vertical 275 and 330 gallon tanks (42"–44" depth) and available in 1-1/2" and 2" Male NPT threads, the unit combines a corrosion-resistant metal body with a thick, UV-stable plastic cap and a free-moving float shaft designed for indoor or outdoor installation.

How do I know this gauge fits my vertical 275 or 330 gallon tank?

The CLLOMAGY gauge was designed to match the dimensions and thread standards used on many vertical heating-oil tanks, including compatibility with Scully Signal Corp Scul-Tel and Intelli-Tank setups. Verify your tank depth and thread size before ordering to ensure a proper fit.

• Compatible depths: 42" to 44" (standard vertical tanks)
• Thread options: 1-1/2" Male NPT and 2" Male NPT
• Works with Scul-Tel and Intelli-Tank vertical sensor systems

What materials and build quality can I expect from the gauge?

This replacement gauge uses a robust steel housing treated for corrosion resistance and a heavy-duty plastic cap engineered to resist UV and impact. The float shaft and internal components are sized to move freely without snagging, helping provide repeatable readings over long service life.

• Steel body for rust resistance and durability
• Thick, UV-resistant plastic cap to resist cracking outdoors
• Float designed to move freely inside the tank for accurate level response

How easy is installation and what should I watch for?

Installation is straightforward for anyone familiar with tank hardware. Insert the float shaft into the tank and screw the gauge assembly into the tank joint. Take a moment to align the float so it can travel along the tank’s length and avoid obstructions.

• Simple screw-in installation to existing tank port
• Align float parallel to tank length for unobstructed movement
• Avoid placing float near fill openings or tank ends to prevent binding

What readings and limitations should I be aware of?

The unit provides clear mechanical level indication for heating oil tanks, removing the need to guess inventory. It is not designed for use with diesel fuel or for measuring non-compatible liquids; follow local codes and fuel guidelines when replacing tank components.

• Accurate level readout for heating oil (not for diesel use)
• Mechanical display designed for vertical tank profiles
• Check local regulations before modifying tank fittings

Who is this for: The CLLOMAGY Oil Tank Gauge is intended for homeowners, property managers, and technicians who maintain residential or small commercial vertical 275/330 gallon heating oil tanks and need an affordable, durable replacement gauge. It’s ideal when the original Scully Scul-Tel or Intelli-Tank indicator fails or when you want a reliable mechanical level gauge that tolerates outdoor exposure and basement installations. If you require compatibility confirmation, measure your tank depth and thread size or consult a service pro before purchase.
