Bleeding the fuel system after filter change
If you know on the fuel priming pump when I pump it it is leaking a lot I guess the O ring is shot.
But this part doesn't look like it can be unscrewed apart from the pump assembly with wrench like I saw in some pics, looks like all one casting.

Is there a way to service it?
