I am trying to get my Tokheim 300 pump working again. Unfortunately I have some problems with the float and bypass, they get stuck and load the motor down, eventually stopping it. I disassembled the pump and found it full of sludge. Now to reassemble I will have to make gaskets but that's easy. The problem is that the float bypass valve is worn, and the relief valves have lost part of their leather seals, and the rubber check valve is hard and brittle. The gear pump itself is in excellent condition though.
While I realize that most collectors could care less about what's inside the pump I actually use mine to move recycled vegetable oil to fill my dad's car and my truck. The pump was given to me in exchange for scrap 20 years ago, and while not perfect, it has been a sort of family member ever since. I am currently soaking the parts in lye, then acid to remove paint and rust and old sludge so I can repaint everything and reassemble. Any help would be appreciated.
