Vents are intended to provide tank breathing, prevent fuel spillage, relieve excess pressure, and
provide thermal venting in vehicle fuel tanks for which this valve is appropriate. Not all vent s listed
have pressure and thermal relief functions, view tank vent cross reference to determine function
of each vent.

Tank vent valves appropriately selected can be used on diesel fuel aluminum tanks up to 200 gallon
total capacity and diesel fuel steel tanks up to 132 gallon capacity.

Zamak 3 or brass
Typically designed to vent air at 30 SCFH with a tank pressure not more than six inches of H2O.
Varies with vent model; see tank vent cross-reference for detailed information.
Vent will not leak in excess of 0.5 ounces per minute of diesel with the vent in any orientation and diesel

applied at any pressure up to 4 PSIG.
In vents that include pressure relief, the vent will star t to flow with diesel pressure applied bet ween 5

and 10 PSIG, and will flow 1.0 GPM or more of diesel at 10 PSIG.
In vents that include thermal reliefs, the vent will thermally activate and open to atmosphere when

exposed to an enveloping fl ame in accordance with FH WA Title 49, CFR Par t 393 Section 67 (d)(1) that
causes a fuel temperature to rise rate of at least 6° F per minute.
