FEDERAL LAW

183.528 - Fuel stop valves

(a) Each electrically operated fuel stop valve in a fuel line between the fuel tank and the engine must:

(1) Open electrically only when the ignition switch is on; and
(2) Operate manually.

If an electrically operated fuel stop valve is in the fuel system, it must be wired to the ignition switch so it will open only when the ignition switch is on. It must also have a means to manually open the valve in the event of loss of electricity. This is often a slot for a screwdriver to turn the valve.
