Service confusion with Common rail pipework reuse One of the associated issues with high pressure common rail technology is the fact that some manufacturers stipulate the replacement of the associated pipework leading to and from the common rail if loosened/removed. This rule differs between each manufacturer. Some allow for pipework reuse up to 5 times before mandatory replacement(obviously if in a serviceable condition). There are also limited lifespan pipework that must be replaced as stipulated in the service regime regardless of being loosened.
