WARNING: Explosive Fuel!
Gasoline is extremely flammable and its vapors can explode if
ignited. Store gasoline only in approved containers, in well
ventilated, unoccupied buildings, away from sparks or flames.
Do not fill the fuel tank while the engine is hot or running,
since spilled fuel could ignite if it comes in contact with hot
parts or sparks from ignition. Do not start the engine near
spilled fuel. Never use gasoline as a cleaning agent.
Pulse Style Pumps
1. Disconnect the fuel lines at the carburetor and at
the in-line fuel filter. See Figure 9-15.
