Does the spider automatically shut off at a gas pump?

[Cmat20]

Hi all,

My spider is almost back on the road, and it just occurred to me that I have no idea if the car will click off at a pump. Assuming that mine works correctly, does the car have an evap system which will automatically shut the pump off? I've never had an older car before and I don't know when that system first became common.

Thanks for any info!

Mine does. Generally it clicks off too soon and I have to top it off while peering down the filler tube.

Cool! I didn't want to leave the pump on and then have it overflow the tank.

Believe the pump shuts off due to back pressure caused by the fill spout filling.
Nothing to do with the evaporative system in the car.
Filling a gas can causes the pump to shut off too.

Yes its fuel blocking the vacuum port in the gas station nozzle that stops the flow by flipping a diaphragm connected to the trigger releasing it so it prevents any type of vessel being filled from overflowing. Works just as well on Gas Cans, Motor Cycles, etc even though without long fill tubes you may get a little splash when they shut down.

The evap system just provides a container to trap any vapors or overflow if you try to top off the tank and fill it to above the overflow drain tube instead of having it just pour out on the ground.
