Dear Mr. Brennan: This responds to your November 21, 1977, letter asking whether a schoo bus that is propelled by a propane-fueled engine is required to comply with Federal Motor Vehicle Safety Standard No. 301-75, *Fuel System Integrity* (49 CFR 571.301-75).; Paragraph S3 of Safety Standard No.301-75 specifies that the standar applies to school buses that have gross vehicle weight ratings greater than 10,000 pounds and use fuel with a boiling point above 32 degrees F. Since the boiling point of propane is below 32 degrees F, Safety Standard No. 301-75 would not be applicable to a school bus propelled by a propane engine.; Please contact us if you have any further questions. Sincerely, Joseph J. Levin, Jr., Chief Counsel
