Abstract
Abstract Apparatus and a process for permitting the fuel tank of a motor vehicle to be drained periodically to remove accumulated water, dirt and contaminated fuel. The apparatus includes a kit which includes an attaching member which is adapted to be attached to the lower outer portion of the fuel tank. The attaching member has a threaded hole through it and a bolt with a washer is provided which is adapted to be threaded into the hole. After the attaching member has been attached to the fuel tank a hole is drilled through the fuel tank in the central portion of the threaded hole in the attaching member. The bolt and washer effectively prevent leakage of fuel through this hole until the tank is to be drained.

Claim 1
Independent Claim
182 words
A fuel tank adaptor kit for converting an existing fuel tank of a motor vehicle to permit it to be periodically partially or totally drained to rid the fuel tank of contaminants comprising a flat metallic plate attaching member having a threaded hole located through its central portion and a plurality of unthreaded holes located away from the central portion of said flat metallic plate attaching member that extend completely through said attaching member, a threaded member for closing the threaded hole in said flat metallic plate attaching member, an oil resistant washer sized and shaped to fit around said threaded member, screw members adapted to fit into the unthreaded holes to be seated into holes in said fuel tank to secure said flat metallic plate attaching member to said fuel tank, oil resistant washers sized and shaped to fit on said screw members to prevent leakage of fuel from said fuel tank when said screw members and associated oil resistant washers are in place and means for attaching said flat metallic plate attaching member to said fuel tank comprising a cement.
