1. A method of providing fugitive gases to a natural gas engine, said natural gas engine having a principal source of fuel and a secondary source of fuel which secondary source of fuel is different from said principal source of fuel, an air supply for providing air to said natural gas engine and an engine intake associated with said engine, said engine further having a throttle associated with said natural gas engine, said fugitive gases being introduced upstream of said throttle of said engine and downstream of an air filter mounted on said air supply, said method comprising positioning said air filter on said engine intake of said engine, allowing said air filter to create a negative pressure in said engine intake downstream of said air filter and upstream of said throttle sufficient to allow said fugitive gases to enter said engine intake and allowing said fugitive gases to be collected by said negative pressure in said engine intake downstream of said air filter and upstream of said throttle.
