Whenever the gasline hoses are removed (other than for
pressure testing), the battery must be disconnected to
prevent inadvertent activation of the electronic fuel pump.

on the fuel system during which there may be fuel leak-
age, there should be no welding, smoking, open flames,
etc., in the area.

Do not turn the ignition switch to the ON position with
the hoses removed. Gasoline will be pumped by the
electric fuel pump causing a safety hazard.

Gasoline may be under pressure. Place an absorbant
towel under the connector to absorb any gasoline spray
when disconnecting.
