there are two fule hose that go into the fuel tank. The one with the filter goes to the carburator. The second hose doesn't have a filter and goes to the primer bulb. To get to them you'll need to take off the side with the primer bulb. Hope it helps, just finished replacing all my worn out and decaying hoses with the help of my brother all due to a cracked chain oil reservoir that we replaced.
