1-13. PUMPING ASSEMBLY (Continued)
EXHAUST SYSTEM - includes a muffler and protective screen. The exhaust system transfers exhaust gases from
the engine to the muffler. The muffler quiets the sound and reduces the temperature of the exhaust.
PUMP bolted to the engine. Uses power from the engine to pump fuel from the suction (intake) coupling to the discharge
coupling. Includes a volute, impeller, check valve, ground rod assembly, and pump case with suction (intake) and
discharge couplings. The volute houses the impeller which draws fuel in through the suction (intake) coupling and forces
it out of the pump through the discharge coupling. The check valve prevents discharged fuel from running back through
the suction (intake) coupling. The ground rod assembly prevents buildup of static electricity.
BASE ASSEMBLY - provides a movable mounting platform for the engine and pump assemblies.
STORAGE CONTAINER - contains hose assemblies, drum unloader, nozzle assembly, and Y-connectors. The storage
container houses the pump assembly and servicing equipment and serves as a carrying box.
