@brokenbudjet...I disabled thw whole pump and did not found other walve. I will try to soak the pump and see what it does...buth when pump is in my hands and when I moove pump piston up down it sucks oil and gets it on upper side. when i mount it on the saw it wont pump

If annybody of you folks knows where that second walve is please just go to start programs accesories ms paint and draw a circle on one of my pump pictures so I can figure out where that damn walve is
