Gas pump dispense speed

When pumping gas, most stations around here (California) have a little latch you can push to dispense gas and let go of the handle.

.. when you use that latch, does it pump slower? Is it supposed to?

I always feel like it does but figure it's a reasonable question for here.

Thanks folks!

  • The fuel nozzle is a completely mechanical implement - there's nothing electronic about it, and the pump has no idea whether you are manipulating the trigger or using the hold-open.

    Because it's mechanical, however, the way the hold-open is designed needs to allow for further actuation of the trigger mechanism to free up the hold-open lever when your tank is full. Because of this, the highest setting on the hold-open is less than the full actuation of the trigger mechanism.
