It's most likely the fuel pump. You could replace the hose and see what happens, but it sounds more like the fuel pump. I had the identical symptoms with my 80's Evinrude 6 horse.
The fuel pump on most of the 6 horse engines from Johnson/Evinrude is simple to replace and not very expensive.
Do a little searching online and you'll probably find the info you need.
Also, if you remove the enginecover and simply follow the fuel line back from the carb to see where it goes, it should end up at the fuel pump. Depending on year, it may be a square thing about 1.5 inches across and about a half inch thick. It doesn't look like a pump. There may be a screw in the middle of it to remove its cover. Removing the cover reveals a diaphrahgm.
If that's what your're seeing, you've found the fuel pump. Before you go any further, get a replacement fuel pump. Looking at the replacement will tell you pretty much everything you need to know to do the repair, assuming you're reasonably mechanical. Skill level for this does not exceed the skill level required to change the oil on a car...or at least not by much.
