Abstract:
1. A multi-layer primer apparatus, comprising: a flexible body defining an internal chamber to be fluidly coupled to a fuel system, the body comprising: a first layer material having a low permeation characteristic to substantially prevent diurnal emissions from escaping through the body; a second layer material adjacent to the first layer material and 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.
