Recirculating
Recirculation hoses at the inlet manifold and crankcase recirculate
unburned fuel for engine consumption.
SEPARATE FUEL TANK
Two types of separate fuel tanks are used. Smaller engines
use the 3.1 gal [12 L] separate fuel tank. Larger engines use
a 6.6 gal [25 L] separate fuel tank. Both tanks have filler caps with
an integral fuel gauge and manual vent screw, and a fuel pick-up
pipe with a hose quick connector.
Cleaning
Water or dirt in the fuel tank can cause fuel starvation and engine
problems. Clean and inspect fuel tank once a year or after long time
storage (more than 3 months).
1. Disconnect fuel line from fuel tank.
2. Empty remaining fuel from tank and properly dispose.
3. Fill tank 1/4 with fresh gasoline and install cap. Rigorously shake
tank for 30 seconds to loosen dirt particles.
4. Empty gasoline from tank and properly dispose.
5. Inspect tank components before refilling.
