Abstract
A flame arresting system for a centrifugal fuel pump of a variety including a downstream impeller and an upstream inlet port. The system includes an arrestor body which is received with the inlet port within an associated fuel tank. The body is formed of an open-cell foam material having an average pore size and thickness selected as being both fluid permeable and adapted to prevent flame from propagating therethrough. The inlet port is contained within the body such that fuel within the fuel tank may be drawn into the inlet port through the arrestor body, with flame being prevented from passing into the tank from the inlet port.
