Leaking roller pump

[Twotengame]

I have a Wylie sprayer that is powered by a Delavan 4-roller pump. There is a small hole in the pump housing that is leaking fluid when the pump is in use. Otherwise, the sprayer is working great. I don't like losing the fluid and when spraying for weeds I'm leaving a trail next to the fence lines.

Any suggestions?

Bad shaft seal.

Makes sense...thanks.

The Hypro roller pumps are really simple to work on, and from their photos and videos, it appears that the Delavan is, too.
