Subaru, Toyota 86 fuel pump can quit while driving high
The low-pressure fuel pump sits inside the gas tank and pushes fuel toward the engine. In these vehicles that pump can fail. If it quits, the engine can stall and shut off while you are driving, and you would lose engine power with little warning. A stall in traffic, at highway speed, or in an intersection can easily lead to a crash. The dealer replaces the pump inside the tank with a new one.
