To replace the pump head seal
1. Insert the seal removal end of the small seal tool in the seal cavity on the pump
head.
The seal removal end is long and thin. It has a barbed tip to catch the seal.
2. Pull the seal out of the head.
3. Place the new seal on the other end of the seal tool.
The seal insertion end is shorter than the removal end. The tip is smooth, not
barbed like the removal end.
4. Carefully align the seal with the seal cavity on the pump head.
5. Insert the seal tool in the pump head so that the open side of the seal enters
first and push until the seal is completely seated in its cavity.
