Fuel nozzle keeps clicking off while refueling

Informational, low priority

gas pump keeps stopping · hard to fill up tank fully

Symptom description

The fuel pump nozzle repeatedly clicks off as if the tank is full, well before it should be, making it hard to fully refuel.

Common causes

  • A blocked or restricted EVAP vent line preventing air from escaping the tank as it fills
  • A fault in the fuel filler neck or its internal flap
  • A clogged charcoal canister in the evaporative emissions system

What to check

Try filling more slowly at a lower flow setting if the pump allows it - if that avoids the clicking, it supports an air-venting restriction as the cause.

Can you keep driving?

Safe to drive with a partial tank, but get the vent system checked if it happens consistently, since you may be unable to get a full range from your tank.
