Abstract

A first and second baffle formed of a thin sheet metal material are introduced into an engine induction system on the upstream side of air fuel metering device and interposed between the air fuel metering device and a tubular intake runner in order to prevent post engine shut down fuel boiling. The first and second baffles absorb heat from the induction system and dissipate heat to the surrounding atmosphere. The first and second baffles are sized sufficiently large to limit peak fuel temperature in the fuel metering device 130.degree. F. when a hot engine is shut down in a 70.degree. F. environment.
