Dear Mr. Utsunomiya: This is in response to your letter of May 9, 1974, requesting a interpretation of the test procedure specified in Standard No. 301 (Docket No. 73-20, Notice 2) concerning the operation of the vehicle's fuel pump during testing.; Paragraph S7.1.3 of the standard requires that electrically driven fue pumps be in operation during the barrier crash tests if they normally operate with the activation of the vehicle's electrical system. If the pump is incapable of functioning with the independent activation of the electrical system and requires the operation of the vehicle's engine, then the pump should not be running during the barrier crash tests.; Based upon the description you provide in your letter, it appears tha you should conduct your barrier crash testing without operating the fuel pump.; Yours truly, Richard B. Dyson, Assistant Chief Counsel
