A spider that likes to nest under the hood of vehicles sounds harmless enough, but it can cause trouble - especially when their cocoon-like webs are dense enough to potentially block fuel vapor lines, which can lead to engine damage and diminished vehicle performance.

Ford's patented screen, a little wider and a little shorter than your small finger, prevents spiders from entering the fuel lines but maintains air and vapor flow.

There is a common spider in North America, known as the yellow sac spider, that seeks out small apertures to build a web cocoon for laying eggs and taking shelter. In vehicles, that often leads it directly to a fuel vapor line. A strand of a yellow sac spider web is as strong as an equally thick strand of steel.

"We’re always working to improve and adapt to whatever the environment or the regulatory regime throws at us," Ford fuel systems engineer David Gimby said.

Ford engineers unleashed the yellow sac spider on test vehicles to give them a chance to observe the spiders occupation of the vent lines. They developed a solution in the form of a new cylindrical "spider screen," which is being installed on all Ford vehicles globally starting with the 2016 Focus RS.
