Abstract

A fluid leak limiter for a high-pressure fuel injection system is disclosed. The fluid leak limiter may have a body at least partially defining a central bore and having a fluid inlet and a fluid outlet, a piston reciprocatingly disposed within the central bore, and a spring located to bias the piston toward a first flow-blocking position at which fluid from the fluid inlet is inhibited from flowing to the fluid outlet. The fluid leak limiter may also have a pin configured to selectively lock the piston in a second flow-blocking position at which fluid from the fluid inlet is inhibited from flowing to the fluid outlet.
