I I m m p p o o r r t t a a n n t t : : The factory installed fuel tank air vent must be in place and functional for the Thermo King unit's fuel
system to operate correctly and for the fuel tank to remain in compliance with Federal Motor Carrier Safety
Administration specifications (title 49, paragraph 393.67). A plugged or restricted fuel tank air vent can
result in premature damage to the fuel pump and could also cause severe damage to the fuel tank. NEVER
remove or install any other component in place of the fuel tank air vent.
