Mike is right.
If the motor and pump running have to be the fluid 50% of the time and 50% the pump in your case.
If you need a new assembly, will be $300-700.
If you are in need for one I will try to find the best deal out there for you.
If they respect you, respect them. If they disrespect you, still respect them. Do not allow the action of others to decrease your good manner, because you represent yourself not others.
