Description

Injector Pipe – No.4 is a high-pressure fuel line in the injection system of the 2.5L 4-cylinder diesel engine.

It forms part of the set of rigid steel pipes that carry fuel under injection pressure from the mechanical fuel injection pump to each cylinder’s injector nozzle. This pipe serves cylinder number four and must be routed and seated correctly at both ends to maintain a leak-free connection under the high pressures generated during injection. Replacement is typically required when the pipe shows signs of cracking, chafing, or seeping at the unions.
