Anti Siphons are guaranteed for the life of the fuel tank they are installed in. They do not restrict fueling and there is no splash-back. Over 800,000 in use!
These patented snap-in Anti-Siphons are an inexpensive and effective solution to help prevent fuel theft. Made in the U.S.A. from the finest quality materials, these Anti-Siphons are designed to foil the most determined fuel thief.
