6.6 Gasoline Fuel Systems

Due to code restrictions which do not allow storage of more than one gallon (3.8 L) of gasoline inside a building, gasoline fuel systems are usually limited to housed generator sets installed outdoors or portable trailer-mounted units.

Gasoline will deteriorate if stored for more than six months, so storage tank size should be kept to the minimum required by code. Engine fuel pumps usually will lift fuel up to four feet (1.20 m) or draw it horizontally up to 20 feet (6.01 m). Auxiliary electric pumps powered by the engine starting-battery can be connected in series with the engine pump. See Figure 6-4. Auxiliary pump pressure should be limited to approximately 5 psi (34.5 kPa). If the auxiliary pump is located at the fuel tank, horizontal and vertical distance limits of approximately twice those for a lone engine pump are practical.

Fuel supply lines should be Schedule 40 black iron pipe, steel tubing, or copper tubing. Galvanized pipe and fittings are not recommended. Line size should be kept to the minimum necessary for the required flow.

Flexible connections at least six inches (15.3 cm) in length should be used between stationary piping and the engine fuel inlet connection.

WARNING

Explosive fuel vapors.

Can cause severe injury or death.

Use extreme care when handling, storing, and using fuels.

Combination natural gas-gasoline fuel systems are sometimes used with gasoline as a standby fuel to meet code requirements for on-site fuel supply. Such systems are not recommended unless the engine will be operated on gasoline often enough to ensure that fuel does not deteriorate and the carburetor will not be disabled by accumulated gum and fuel deposits.

If a fuel storage tank is located above the engine, an anti-siphon fuel solenoid valve or air bleed hole in the fuel tank dip tube (near the top of the tube inside the tank) should be used to prevent siphoning.
