Performance

Application

The 2989-11 high-ﬂow vent is 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. It is

speciﬁcally designed to work with new engines that generate a high volume of vapor returning to the

tank, and to maximize the probability that the vent will re-open even after closure by fuel slosh and

pressurization by returning vapor.

Limitations

This tank vent valve is designed for use on diesel fuel aluminum tanks up to 200 gallon total capacity

and diesel fuel steel tanks up to 132 gallon capacity.

Air Venting

Designed to vent air at 70 SCFH with a tank pressure not more than 18 inches in H2O. Will vent in excess

of 100 SCFH air without corking (closing).

Unseating

Once closed and upright, in the absence of fuel, vent will partially unseat (re-open) at a descending

pressure at or above 40 inches H2O.

Anti-Spill

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.

Thermal Relief

At 255°F, vent will thermally activate and open a 0.56 Diameter hole to atmosphere when exposed to

an enveloping ﬂame in accordance with FHWA Title 49, CFR Part 393 Section 67 (d)(1) that causes a fuel

temperature to rise at a rate of at least 6° F per minute.

Pressure Relief

Pressure relief feature will start to ﬂow with diesel applied to between 4 and 8 PSIG, and will ﬂow 1.0

GPM or more of diesel with 10 PSIG.

Barb Alignment

Barb may be aligned after installation by rotating without disturbing thread alignment.
