67 Charger Fuel fill hose/clamps

[Charger Too]

Received 4 clamps for the fuel fill elbow hose. I realize 2 at each end, but are they to be spaced out a certain way? Also, why four clamps? Thanks!

Aftermarket engineering. Must have had leaks so double up.

Factory used one clamp per end.

Today's hoses, place one clamp just before the ridge and one just after the ridge. There will be a ridge in both connecting pipes.
