Early a body filler neck flapper install

Why do you want that ?

Gas pump kick off. It’s a restoration project for my 16 year old son, and member here.

I remember on mine, before the fuel cell, gas pumps blowing fuel all over my quarter panel. Lol.

This device is suppose to stop this by allowing the fuel to back up into the nozzle when full and kick the pump off.

I figured it would just slip in and be easy. Lol.
