General Motors Capless Fuel Filler Technology

Capless Fuel Fill is a General Motors convenience technology that makes fueling a vehicle more convenient.

How It Works

Vehicles equipped with the GM Capless Fuel Filler system do not have traditional twist-off gas caps. Instead, these vehicles have a set of two doors, each locking fuel in with a rubber seal around its edge.

When a fuel nozzle is inserted, the nozzle pushes these doors, which are designed to assure the system will remain airtight through years of use.

How To Use It

How to use Capless Fuel Filler at the pump:

  • Turn off the vehicle’s engine and leave cell phones inside the vehicle
  • Open the fuel door
  • Insert the fuel nozzle slowly and wait for any hissing noise to stop prior to pumping fuel
  • Drivers should stay with the vehicle while refueling
  • Overfilling the fuel tank by more than three clicks of a standard fill nozzle may cause performance issues, fuel spills or potential fuel fires
  • Wait a few seconds after refueling is complete before removing the nozzle and closing the fuel door

How to use capless fuel filler with a portable gas can:

  • Locate the capless funnel adapter from inside the vehicle (typically found in the trunk of a car, truck or SUV and under the rear seat in a pickup truck)
  • Insert and latch the funnel into the capless fuel system
  • Remove and clean the funnel adapter and return it to the storage location

Benefits

The GM Capless Fuel Filler delivers the following benefits:

  • No fuel cap to use
  • Helps keep hands free of dirt and fuel
  • Helps prevent disruptions to the closed fuel system and “check engine” service visits
  • No dangling fuel cap to scratch painted surfaces while fueling and no caps to potentially forget when driving off without closing it
  • Mechanisms in the fuel filler neck make it nearly impossible to siphon more than a few gallons of gas
  • A vapor recovery system built into the fuel filler means fewer fumes escape to pollute the air
