I don't believe that is correct, Don. At least some cars had push-on hoses with black fabric braid on the outside of the rubber.
Johnny, that 'sump' is the float bowl, an important part of the carbs. It is soft mounted on some rubber seals that perish easily (and let fuel drip onto the hot exhaust manifold), so you want to be careful about how much force you apply to the bowl without supporting it. But you should be able to firmly grip the hose with pliers and twist it back and forth to break the seal and work it off.
Afterwards, as Don says, I would suggest replacing with modern nitrile fuel line (the originals won't stand up for long to what passes for gasoline in the US these days), and small hose clamps, moderately tightened. The modern lines won't grip as tightly as the originals did, making the clamps mandatory IMO.
Personally, I also like to replace all the soft fuel lines every decade or so, just because they can get old and break internally without looking particularly bad from the outside. Little flakes of rubber from inside the hose can get into the float valves and block them open, causing the float bowls to overflow (generally while you are stopped in heavy traffic
)
