Abstract
Primer apparatus and methods are described herein. An example primer apparatus includes a flexible body defining an internal chamber to be fluidly coupled to a fuel system. The body includes a first layer material having a low permeation characteristic to substantially prevent diurnal emissions from escaping the fuel system, a second layer material adjacent the first layer material having a relatively high resiliency compared to the first layer material to enable the body to return to an uncompressed shape when the body is deflected and released by a user, and a third layer material adjacent to the first layer material such that the first layer material is disposed between the second layer material and the third layer material and having a relatively high resiliency compared to the first layer material to enable the body to return to the uncompressed shape when the body is deflected and released by the user.
