FILL PIPE ANTI-SIPHON DEVICE AND METHOD OF USE

摘要

A device and method of use for a fill pipe anti-siphon device are described. The device and method of use are designed to provide a simple, reliable, cost-effective means to prevent theft of fuel or other liquids from holding tanks, such as a fuel tank on a semi-tractor trailer diesel truck, by siphoning. The device is a barrier which prevents insertion of a siphon hose or tube of suitable diameter to efficiently siphon fuel of other liquid from a tank. The barrier device allows for the simultaneous filling of a tank through a fill pipe neck while venting an from the tank at a sufficient rate to prevent or minimize backflow of fuel or other liquid during fueling or tank filling from the tank when using a high-flow fill nozzle.
