2. Loosen hose clamp and remove hose.
3. Remove the In-tank filter from the pressure chamber.
4. Remove 2 bolts attaching the pivot lever to the pump shaft and remove piston assembly (fig. 2a & 2b).
5. Remove large clamp holding the pressure chamber and tank together (fig 1).
6. Rock the pressure chamber back and forth and push down to free it from the tank (fig 1).
7. Once freed the entire pump assembly can be removed by maneuvering it through the base frame
(fig 3a & 3b).

Assemble the o-ring over the top of the chamber. Apply petroleum jelly to the o-ring before reinstalling pump
asembly into the tank (fig. 3b).
