Run your numbers
What a tampering incident costs you
Most operators underestimate this, because they price a single incident and stop. The number that matters is annual exposure across every position on the site.

Fuel value only. It excludes pump damage, downtime, the labor to reconcile the loss, and the inspection or recalibration a tampered dispenser may need before it goes back in service.
Reality check
Where those default numbers come from
The calculator starts at 900 gallons per incident. Here is the reported range.
stolen across 70 retail locations in a single Florida theft ring — $650,000 in losses.
taken from one Tennessee station’s unattended pumps — $63,000 of diesel.
hit by one crew using a device to override pump software, Napa to Monterey.
The low end matters more than the high end. A crew working a route of 15 stations averaged roughly 700 gallons per site — small enough that several of those operators may never have booked it as theft at all. See fuel shrinkage red flags.
What the number leaves out
The fuel is the cheapest part
Pump damage and repair
One Palm Beach County station reported roughly $1,000 in damage from a single incident where the crew was interrupted and got nothing. Damage does not scale with fuel taken.
Downtime on the position
A dispenser whose metering is in question should not be selling. Every hour it is bagged is throughput you do not get back, plus the inside sales that came with it.
Inspection and re-verification
Depending on your state, a unit with compromised metering may need re-verification or resealing before it can legally sell again. That is a scheduled visit, not a phone call.
The labor to find it at all
Reconstructing weeks of reconciliation, pulling footage, filing the report, working the claim. This lands on whoever is already busiest.
Why it hides
Your dispenser is not a witness
At a business level — no mechanism detail here, deliberately — this is the part operators find counterintuitive, and it is the whole reason these losses run for months.
The pulser is the component that counts. Everything downstream of it inherits its number: the display, the transaction, the POS total, the end-of-day report. When the counting component itself is interfered with, the dispenser reports a normal sale.
So a reconciliation process that compares POS totals against dispenser totals is comparing two numbers drawn from the same source. They will always agree. They will agree while you are being robbed.
The only number that comes from somewhere else is what actually left the tank. Tank-to-dispenser reconciliation is where a metering discrepancy has to show up, and for a lot of sites it is the one comparison nobody runs.
Reconciliation red flags
- Variance that only ever goes one direction over 90 days
- A step change with no operational cause on that date
- Loss concentrated in one grade, usually diesel
- Overnight accrual at an unattended or low-traffic site
- Tank drops that disagree with dispenser totals
- Repeat "false" cabinet alarms on the same position
If you suspect an incident
Do these four things first
- Take the dispenser out of service. Do not keep selling from a unit whose metering is in question.
- Do not open the cabinet. You will destroy evidence, and you may not be equipped to assess what is in there.
- Call the police and get a report number. Your insurer will ask for it, and regional patterns get tracked from these.
- Call your fuel equipment service provider. They inspect it and tell you what has to happen before it goes back in service.
