Husqvarna chain saw 359 oil leak?

Oil leaks really bad from chain oiler It will leak out even when saw is not in use.
I was able to get to the oil pump by putting rope through the spark plug hole to stop the piston,and take the clutch off" Not a good design".
I took off the little pump the hose that feeds it came out a little bit and oil came out from behind it.
Has the oil line came loose from the oil tank?
Can I easily repair this myself?
