The F8U-1 (F-8A), the F8U-1P (RF-8A), and the F8U-1E (F-8B) were not equipped with underwing hard points or pylons, and therefore no plumbing in the wings for fuel transfer.
So no... the F8U-1 could NOT be fitted with drop tanks.
In fact, the F8U-2 (F-8C) and the F8U-2N (F-8D) weren't fitted for underwing hardpoints/pylons either.
It was only with the F8U-2NE (F-8E) that the Crusader could finally carry anything under its wings.
