You Monitor Your Tires With TPMS — But Who's Monitoring Your Fuel Cap?
If you've installed a TPMS, you understand the value of protecting expensive systems before something goes wrong. A tire blowout can cause $5,000–$20,000 in damage. But while your tires are monitored 24/7, your fuel cap sits completely exposed and unmonitored.
The Protection Gap
| System | Threat | Protection | Cost of Failure |
|---|---|---|---|
| Tires | Blowout | TPMS ($150–$400) | $5,000–$20,000 |
| Electrical | Power surge | Surge protector ($100–$400) | $500–$3,000 |
| Fuel | Theft, contamination | Nothing | $200–$15,000 |
