GMC Safari fuel filling issue with pump clicking off every 10 cents on GMC Safari

Some GMC Safari owners report experiencing issues with the gas pump clicking off every 10 cents while trying to fill up. This problem is often linked to a faulty vent valve in the evaporative emissions control system, which can cause back pressure in the filler neck and lead to intermittent pump shut-offs. Additionally, overfilling the fuel tank may saturate the charcoal canister, further complicating the evap system. Owners also encounter issues with clogged vents that prevent proper air release as the fuel level rises. To mitigate these problems, it is advisable to check the vent valve and the emissions control system for faults, avoid overfilling the tank, and inspect the vent hose for kinks or blockages. Addressing these potential causes can help resolve the frustrating issue of the gas pump repeatedly clicking off.
