A tank connection includes a tank formed with a plastic wall having multiple thicknesses, a first thickness being substantially impervious to hydrocarbon permeation, the wall having an opening surrounded by an edge of the wall, a component secured by a weld to an outer surface of the wall, and seal substantially impervious to hydrocarbon permeation, contacting a surface of the component, and biased into elastic contact with said edge.
