Abstract
A fuel insertion tube tool for installing a fuel tube on a barb. The tool has first and second arms that are pivotably attached through an arm pivot axis. Each arm has a grip to engage the fuel tube. A tab extends from the first arm and is pivotably attached to a proximal end of a bar with a pivot pin that defines a bar axis. The bar axis and the arm axis are perpendicular to each other. A hook is disposed at a distal end of the bar for engagement with an attachment site. The tab functions as a fulcrum to reduce the amount of force required to install the fuel tube on the barb. The bar has weight reducing holes and the grips have straight knurls for frictional engagement with the fuel tube.
