TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your letter of October 14, 1975, in which you request an interpretation of Standard No. 301 as it applies to a vehicle with an electric fuel pump that operates only when the ignition switch is in the "ON" position and the engine oil pressure is within the normal operating range.

You indicate in your letter that, in effect, the fuel pump can only operate when the vehicle's engine is running. Paragraph S7.1.3 of Standard No. 301 requires that an electrically driven fuel pump be operating at the time of the crash tests if the pump "normally runs when the vehicle's electrical system is activated." It appears from your letter that activation of the electrical system by switching the ignition to "ON" will not by itself activate the fuel pump. As a result, the pump need not be operating at the time of the crash tests.

SINCERELY,

October 14, 1975

This is to request your official interpretation as to the applicability of S7.1.3 of F.M.V.S.S. 301 to the system described below.

The fuel pump is electrically driven but operates only when the ignition switch is in the 'ON' position and the engine oil pressure is within the normal operating range. The engine must be running in order to produce this condition.

Your earliest response in this matter would be appreciated.
