Abstract
A tamper-resistant seal is disclosed for discouraging unauthorized access to an adjusting screw located in a fuel injection pump. The seal includes a bracket secured by one-way fasteners to the pump and is positioned adjacent to the adjusting screw. The bracket also includes a stud projecting outwards from its outer surface. A cover having an aperture formed therein is positioned over the bracket such that the stud passes through the aperture. When so aligned, the cover will completely enclose the one-way fasteners and the adjusting screw thereby preventing access to them. The cover is secured to the bracket by a fastener which locks onto the stud. The fastener prevents the removal of the cover from the bracket without physically destroying the seal. Such a seal is beneficial in providing visual assurance to the manufacturer that his pump has not been tampered with.
