This is the Oil Supply Pipe that supplies oil from the Engine block to the Injector Pump and the Vac Pump. Due to constant engine vibration and heat, the original pipe can develop cracks, or the banjo fittings can begin to leak oil. Failure to replace a leaking or damaged pipe will starve these essential components of lubrication. This can cause catastrophic failure of the expensive injection pump and a complete loss of braking assistance from the vacuum pump, which is a major safety risk.
There is also a double washer located on either end of this Pipe for the ZD30 engine that is available seperately in our online store: 151892W20B
