TITLE: FMVSS INTERPRETATION

TEXT: Thank you for your letter of August 19, 1976, to Dr. James D. Gregory, requesting information on aftermarket gas caps as they relate to compliance with Federal Motor Vehicle Safety Standard (FMVSS), No. 301. Your inquiry has been forwarded to this office for reply. Apparently your letter of May 26, 1976, was either lost or misdirected, as we can find no record of it in our files, and we sincerely apologize for this delay in responding to your inquiry.

The National Highway Traffic Safety Administration does not regulate vehicle fuel tank caps as such; however, FMVSS No. 301, Fuel System Integrity, specifies performance requirements to assure the integrity of the entire vehicle fuel system (which includes the fuel tank cap) in various crash modes.

Thus, if installation of your replacement cap is accomplished prior to the first purchase of the vehicle for purposes other than resale causing the vehicle's fuel system not to be in compliance with the applicable safety standard, the person installing the cap or offering the vehicle for sale would be in violation of S103(2)(1) of the National Traffic and Motor Vehicle Safety Act (Pub. L. 89-503). That would make the installer or seller subject to civil penalties of up to $ 1,000 for each violation.

Recent amendments to the Traffic Safety Act (Pub. L. 93-492) prohibit any manufacturer, distributor, dealer, or motor vehicle repair business from knowingly rendering inoperative, in whole or in part, any device or element of design installed on or in a motor vehicle or item of motor vehicle equipment in compliance with an applicable motor vehicle safety standard (S108(a)(2) (A)). Thus, it is illegal for any of the above named persons to install a fuel tank cap that he knows will cause the vehicle to be in non-compliance with the fuel system integrity standard. Federal Law does not, however, prohibit the owner of a vehicle from purchasing and installing a fuel tank cap of his choice on his own vehicle, even though he may compromise the Fuel System Integrity Standard.

We are interested in any information regarding safety problems associated with replacement gas caps as a basis for further action. If you could provide any such information, we would be most grateful.

Thank you for sharing your thoughts with us.

SINCERELY,

May 26, 1976

James B. Gregory, Administrator U.S. Department of Transportation National Highway Traffic Safety Administration I am writing to you for some clarification on Motor Vehicle Safety Standard No. 301-75 (part 571; S 301-75. This standard spells out original equipment manufacture's responsibilities for designing automobiles against fuel spillage after crash tests. This implicitely means that manufactures of gas caps for OEM customers are required to provide gas caps which conform to the roll-over requirements.

My question is, do the Federal Motor Vehicle Standards in any way impose requirements on parts manufacturers who make gas caps for after-market retail outlets to market caps which meet the OEM roll-over specifications?

For any company to volentarily follow the practice of meeting the roll-over specifications when others do not, self-imposes a severe marketing penalty because of the additional large number of caps which are needed for complete market coverage. This poses warehouse customer inventory stocking problems. Since some companies are using one cap for the OEM which meets roll-over requirements, and a different cap for the after-market at a decided competative advantage, it is imperative to us that this question of applicability of the Federal Motor Vehicle Safety Standard be answered.

I await your early reply.
