Business and Consumer Protection California 4 Minutes Read ยท published February 08, 2026 Flag of California

In Fresno, California motorists and business owners rely on accurate fuel pumps for fair transactions. Local enforcement of pump accuracy is handled through official weights and measures authorities; this guide explains how to check a pump, report a suspected error, request official testing, and what to expect from enforcement and appeals.

Overview of Authority & Scope

Fuel pump accuracy is regulated by state standards enforced locally by the county sealer of weights and measures and supported by the California Division of Measurement Standards. For Fresno the primary enforcing office is the Fresno County Agricultural Commissioner / Sealer of Weights & Measures[1]. The state office maintains measurement standards and guidance for local sealers[2].

How to Verify a Pump Yourself

Before filing a complaint, perform simple checks to document a suspected inaccuracy:

  • Record the pump number, station name, date and time.
  • Buy a small, known quantity and keep the receipt.
  • Compare the displayed gallons and price to expected volume for the fuel dispensed.
  • Photograph the pump meter, nozzle, and receipt if safe to do so.
Keep calm and gather clear evidence before contacting authorities.

Reporting and Official Testing

To request an official inspection or testing, contact the Fresno County Sealer of Weights & Measures. The sealer can perform an on-site test using certified test measures and may apply seals or remove a pump from service if it fails. City consumer offices may direct complainants to the county sealer for measurement issues[3].

What to Expect

  • An intake or complaint record will be opened and an inspector scheduled.
  • Inspectors test pumps with certified test measures and document readings.
  • Pumps that fail may be sealed, disabled, or require repair and re-test.
Inspectors use certified measures to compare dispensed volume against meter readings.

Enforcement authority: Fresno County Agricultural Commissioner / Sealer of Weights & Measures enforces measurement accuracy and may issue administratively assessed penalties, orders, or remove equipment from service. The California Division of Measurement Standards provides regulatory oversight and standards for tests[2].
