Honda is recalling more than 720,800 vehicles in the U.S. over concerns that a high-pressure fuel pump may crack and leak fuel, the National Highway Traffic Safety Administration said on Tuesday.

A cracked core component in the fuel pump can lead to fuel leaks, increasing the risk of fire if an ignition source is present nearby.

Honda has recalled 720,810 cars for cracked pumps that can cause fuel leaks. This is the second major recall from Honda this month.
