I have had a PB smoke pump in my CARF Tutor for a year, works perfectly.

How can you tell it's not seized? The main problem we have had with smoke pumps is debris or slight corrosion from moisture in the fluid sticking the steel gears. Remove the pump and try and manually pump some fluid through the nipples, Any crud coming out the opposite side will tell you there is a blockage. If not send it back and we will get it too PB
