CLLOMAGY Oil Tank Gauge — 42″–44″ Depth (Vertical)
This direct replacement gauge is designed for broken oil tank gauges in oil or fuel tanks. It is a vertical-tank gauge compatible with Scully Signal Corp’s Scul-Tel and Intelli-Tank systems, for tanks with a depth of 42″ to 44″ and 1-1/2″ or 2″ Male NPT threads. It reads oil level at a glance and displays readings clearly, reducing guesswork for homeowners. Best for: homeowners replacing failed gauges on vertical oil tanks in the 42″–44″ depth range.
Limitations: Not intended for diesel use in some listings; verify compatibility with your specific tank model before purchase. Best practice is to confirm the NPT size and tank depth prior to installing.
CLLOMAGY Diesel Gauge — 42″–44″ Depth
This direct replacement gauge reads diesel tank levels in vertical tanks with 42″–44″ depths, featuring 1-1/2″ and 2″ Male NPT threads. It is suitable for Scully Signal Corp Scul-Tel and Intelli-Tank products. Readability and straightforward installation make it a practical option for diesel-only transfer tanks. Best for: diesel-only applications needing a simple, reliable gauge replacement.
Limitation: Data notes diesel readiness; ensure your tank is listed as compatible to avoid misfit or leak risks after installation.
Benut Oil Tank Gauge — 275 & 330 Gallon Tanks
Designed for 275 and 330 gallon vertical tanks, this gauge covers depths of 42″ to 44″ and accepts both 1.5″ and 2″ openings. It features an upgraded metal float and a precision linkage system for stable readings. The dial is a clear poly window, making readings visible even in dim utility spaces. Best for: homeowners with mid-size vertical tanks seeking improved accuracy and easy readability.
Limitation: Float placement should avoid proximity to fill ports or end tanks to prevent reading distortions.
Rochester Gauges 7183 Adjustable Fuel/Oil Gauge
This adjustable gauge is suited for cylindrical farm tanks and similar configurations. It mounts in the center of the tank end head with a 1 1/2” MPT connection and can adapt to varying tank shapes. Best for: farm or utility setups using cylindrical tanks where center mounting is preferred for balanced readings.
Limitation: Primarily designed for stationary or mobile horizontal cylindrical tanks; not ideal for tall vertical tanks with non-standard end heads.
Husky Leak Guard Tank Gauge
This gauge handles a variety of fluids, including oil, waste oil, diesel, antifreeze, and water, with a large 4-window display and an orange UV-inhibited indicator for easy readability. It uses 2″ NPT threads, with a 1.5″ version available separately. Best for: users needing a versatile gauge capable of monitoring multiple fluids in mixed-use tanks.
Limitation: The standard 2″ connection may not fit smaller tank openings; verify thread size before ordering.
Krueger Sentry Gauge H-2-48
The H-2-48 gauge is built with galvanized steel rods, HDPE floats, and an aluminum bushing, designed for rugged farm or industrial tanks. It uses a 2″ NPT connection and is suitable for depth up to 48″ in certain configurations. Best for: harsh environments where durability and longer float travel are required.
Limitation: Designed for specific tank heads; confirm mounting compatibility with your tank end head before purchase.
Buying Guide: Key Considerations For Choosing A Fuel Gauge For Transfer Tanks
- Tank type and orientation: Vertical vs. cylindrical horizontal tanks require different mounting styles and float mechanisms. Confirm depth range (commonly 42″–44″) and head space.
- Thread size and openings: Most gauges use 1-1/2″ or 2″ NPT fittings. Verify your tank’s opening size before buying.
- Fluid compatibility: Ensure the gauge is compatible with oil, diesel, or other fuels, especially if you mix fuels in transfer systems.
- Readability: Look for clear dials or large display windows, especially if the gauge will be mounted in basements or utility rooms.
- Durability: For outdoor or farm setups, corrosion resistance and sturdy mounting are important. Consider galvanized or steel components where applicable.
- Installation considerations: Some gauges require direct mounting to tank heads; others offer center mounting or inline configurations. Check installation instructions for clearance and brackets.
- Maintenance and replacement: Choose gauges that are straightforward to replace or upgrade without draining the tank.
Frequently Asked Questions
- What depth range do most transfer-tank gauges cover? Most gauges target 42″–44″ tank depths, with some accommodating up to 48″ or more depending on design.
- Can I use a vertical-tank gauge on a horizontal cylindrical tank? Not typically. Horizontal tanks usually need gauges designed for cylindrical ends and center mounting.
- What is the difference between 1-1/2″ and 2″ NPT gauges? This refers to the thread size that fits the tank opening. Match the gauge thread to the tank port for a proper seal.
- Are all gauges suitable for diesel and gasoline? Some gauges are listed as compatible with diesel or specific fuels; always confirm fluid compatibility before installation.
- Do these gauges require professional installation? Most replacements are straightforward for DIYers familiar with basic tank fittings, but consult a professional if you’re unsure about seals or mounting.
- How does a float-type gauge indicate levels? A float rides with the liquid level and connects to a linkage that moves the dial to indicate current fuel level.
