The Homelite 4620 chainsaw has two sizes of fuel line. The large line goes from the large port on the primer button to the fuel tank, and the small line goes from the primer button to the carb. There are two hose connections on the carb, one of which is a vent. The hose can be run from the tank fitting to the Carb fitting, or from the tank to the shut-off valve to the Carb, or from the tank to the shut-off to prime to the Carb, or from the tank to the shut-off to prime to the filter to the Carb. John HOMELITE used the formed fuel line on many models until someone had the idea that it was cheaper and easier to use a straight line and a grommet.

There are two sizes of line. The large one goes to the large port on the primer button and then to the fuel tank. The small one goes from the primer button to the carb.
The large port is on the primer button and the small port is on the carb.
The line at the rear of the fuel tank with the fuel filter is the main feed line to the carburettor and connects to the upper nipple. The lower nipple on the carburettor goes to one of the primer ports.
Shift the line to the other port of the primer and try pumping again. If this doesn't work, remove the main fuel line and return it to the upper carburettor port. Run a new line from the lower carburettor port to the active primer port and try to pump fuel again.
Yes, you can run the hose from the tank to the shut-off valve to the carb, or from the tank to the shut-off to prime to the carb.
