Bambarger, Carl . 1998. Tired of Doing the Exhaust Primer Tango?. 9851 1317. San Dimas, CA: U.S. Department of Agriculture, Forest Service, San Dimas Technology and Development Center. 3 p.

Exhaust primers represent about 25 percent of the priming systems used on wildland fire apparatus. Firefighters who have worked with them to prime for a drafting operation know of the Exhaust Primer Tango. The time required to open the discharge valve and release the primer as the pump motor loads up is exacting and touchy. Success in establishing a prime rarely occurs on the first try. However, the simple fix of adding a check valve will eliminate the frustration and increase the reliability of establishing a prime with this system.
