Siphon Stop System
SmartTank Siphon Prevention Device
How It Works
The Siphon Stop prevents tank contents from draining through the submersible pump when the system is not in use. It uses a check valve design that breaks the vacuum and allows air entry during negative pressure conditions.
Key Features
Breaks vacuum utilizing check valve
Works with submersible pump "tank port" for air entry
Prevents tank contents from siphoning through pump
Stainless steel tubing construction
Why This Matters
Without siphon protection, a leak in discharge piping could drain the entire tank contents. The siphon stop ensures that only the fuel in the piping above the tank can escape in a leak scenario.
Low Mount Fill Container
Complete Fill System with Safety Components
How It Works
The fill container provides a secure connection point for fuel delivery trucks. Located at ground level for safe access, it includes all required safety valves and signage for code compliance.
Included Components
Cam lock fill adaptor for secure connection
Check valve to prevent backflow
Fire-rated API 607 ball valve
Locking drain valve for security
Fill port sign with code-required information
Compliance Note
Fill container signage includes tank capacity, product type, and emergency contact information as required by NFPA 30 and local fire codes.
Tank Identification Decals
NFPA 704 Hazard Diamonds & Product Labeling
NFPA 704 Diamond
The hazard diamond communicates risks to emergency responders at a glance. Red = flammability, Blue = health hazard, Yellow = reactivity, White = special hazards. Numbers 0-4 indicate severity.
Decal Specifications
Applied to all four sides of tank
2 mil outdoor grade 3M vinyl
Permanent 3M Controltac adhesive
3 mil gloss over-lamination
5-7 year life expectancy
Compliance Note
NFPA 704 placards and product identification are required by OSHA, NFPA 30, and local fire codes. Proper labeling enables emergency responders to quickly assess hazards.
Tank Construction Comparison
UL 2085 Fireguard® vs UL 142 Flameshield®
UL 2085 Fireguard® (Protected Tank)
Lightweight thermal insulation between walls
2-hour fire rating at 2,000°F
Ballistics and vehicle impact tested
3-6" larger diameter than UL 142
~1.5 lbs per gallon heavier
Required by most jurisdictions
UL 142 Flameshield® (Secondary Containment)
Double-wall steel without insulation
Passes 2-hour fire test (non-insulated)
Emergency vents prevent failure
No documented fire failures with proper venting
$1.50-2.00/gallon less than UL 2085
Requires AHJ approval
Our Recommendation
Budget for UL 2085 unless your AHJ confirms UL 142 is acceptable. We're happy to consult with your Authority Having Jurisdiction on your behalf.
Emergency Vent
UL Listed Pressure Relief Device
How It Works
In a fire condition, pressure builds inside the tank as fuel heats and vaporizes. The emergency vent opens at a preset pressure to safely release vapors, preventing the tank from becoming over-pressurized and possibly rupturing.
Key Features
Spring-loaded design opens at preset pressure
Safely releases vapors to prevent rupture
Self-reseating after pressure normalizes
Sized to tank volume and fire exposure area
Flanged mounting for secure installation
Why This Matters
After a tank explosion in Kerrville, Texas in the 1950s, UL required emergency venting on all tanks. Since then, there has not been a documented failure of a properly-equipped UL 142 tank due to fire exposure.
Mechanical Clock Gauge
Morrison Bros. Model 918S
How It Works
Dual stainless steel floats inside the tank rise and fall with fuel level, connected via cable to the clock-style dial. The dial reads in feet and inches for precise level indication.
Key Features
Easy-to-read dial calibrated to tank dimensions
Stainless steel floats "†no cork to deteriorate
Float-actuated mechanical design "†no power required
Weatherproof enclosure for outdoor installation
Proven reliability across 1,000+ installations
Why We Specify This
After decades of experience, the Morrison Bros. clock gauge has proven extremely robust and dependable. Electronic ATG systems are available but add significant cost for conduit and remote annunciators.
High Level Alarm
Intrinsically Safe Overfill Warning
How It Works
The high level alarm activates at approximately 90% tank capacity during fuel delivery, providing an audible alert to the delivery driver before the mechanical overfill prevention valve engages.
Key Features
Activates at ~90% tank capacity
Audible alarm alerts delivery driver
Battery-operated "†intrinsically safe
Test/Cancel button for verification
Low battery indicator
Compliance Note
NFPA 30 and NFPA 30A require high level alarms on aboveground storage tanks to alert operators during filling operations.
Interstitial Leak Indicator
Morrison Bros. Model 724
How It Works
The interstitial space between tank walls is maintained at a slight vacuum or pressure. The gauge continuously monitors this space "†any change indicates a potential leak in either the primary or secondary tank wall.
Key Features
Visual gauge indicates interstitial pressure
Detects leaks in either tank wall
No power required "†mechanical operation
Continuous monitoring "†check at a glance
Alarm contacts available for remote monitoring
Early Detection
Interstitial monitoring provides early leak detection before product escapes secondary containment, allowing repairs before environmental impact occurs.
Overfill Prevention Valve
Mechanical Float-Actuated Protection
How It Works
Installed inside the tank on the fill line, the overfill prevention valve uses a float mechanism to restrict flow when fuel reaches 90% capacity. At 95% capacity, the valve closes completely.
Key Features
Two-stage operation (restrict at 90%, shut off at 95%)
Float-actuated mechanical design
No power required "†fail-safe operation
Works regardless of operator attention
Why This Matters
Prior to mechanical overfill prevention, overfills were the #1 source of spills from aboveground tanks. These valves enabled double-wall tanks to replace diked containment areas.
Submersible Turbine Pump
Franklin Fueling FE Petro®
How It Works
The FE Petro submersible turbine pump sits at the bottom of the tank, fully submerged in fuel. The multi-stage centrifugal pump pushes fuel up through discharge piping to the dispenser.
Key Features
Self-priming design eliminates priming issues
Intake screen filters debris
Check valve prevents backflow
Siphon stop prevents tank drainage
Available in 18-200 GPM flow rates
Standard Flow Rates

Emergency Shear Valve
Dual Poppet Impact Protection
How It Works
Installed at the base of the dispenser, the emergency shear valve is designed to shear cleanly if a vehicle strikes the dispenser. Dual poppets immediately seal both supply and return lines.
Key Features
Installed at base of dispenser
Designed to shear cleanly on impact
Dual poppets seal supply and return lines
Stops fuel flow immediately
Fusible link option for fire conditions
Compliance Note
NFPA 30A requires emergency shear valves at dispensers to prevent fuel spills if the dispenser is struck by a vehicle.

Our Position on UL 142 Safety
Tens of thousands of UL 142 tanks have been manufactured and installed since the standard was established in the 1960s. To our knowledge, not a single properly-equipped UL 142 tank with emergency vents has failed due to fire exposure. Tanks that have failed during fire exposure did not have emergency vents installed.
In our opinion, UL 142 tanks with emergency vents offer sufficient protection. However, manufacturers that only produce UL 2085 tanks have successfully lobbied code authorities to require the higher standard. Most fire codes allow the AHJ to consider alternative protection from exposures, and knowledgeable officials may approve UL 142 tanks based on site-specific conditions.
