Fords are not known for a problem in design here. The cause is probably twofold.

First, the nozzles used for unleaded gas (which is all we have here in the
States) were (and are still) deliberately made smaller than the old nozzles for
leaded gas. Then they made the fueling ports on cars with catalytic converters
smaller, so that you couldn't pump leaded gas into them. When you stick the
unleaded nozzle into the old Falcon fueling port, there's no way it's going to
stay put. You will have to stand there and hold the nozzle in place.

The second problem is the anti-vapor shield that is required in many States. If
the pump you're using has one of these, you won't be able to tilt the nozzle
high enough to get the angle right. These things are a rubberized plastic shield
about 5" square, located at the point where the nozzle joins the handgrip.

I worked at an Esso station from '65 to '67, and we did not have any problems
pumping gas into Falcons.
