Blanking Plug Set for Common Rail Diesel Pressure Checks

A blanking plug set for common rail diesel pressure checks, used when tracing fuel rail pressure loss and non-start faults. It allows individual cylinders to be blanked off one at a time, helping make diagnosis more direct and methodical.

Used during common rail fault finding, this set is suited to workshop servicing, diesel diagnosis and mobile mechanic work where pressure checks are part of the job. When an engine will not start and rail pressure is under suspicion, blanking off each cylinder in turn can help narrow down where the problem may be occurring instead of relying on guesswork. It is particularly useful for technicians and mechanics dealing with regular vehicle maintenance, diesel system checks and repeat diagnostic work.

The set includes 12 plugs in two common sizes: 6 plugs in M12 x 1.5 and 6 plugs in M14 x 1.5. That gives you options to suit different common rail applications while keeping the parts together in one dedicated set. For anyone carrying out diesel pressure testing on a regular basis, having both sizes close to hand helps keep the process organised and saves time when moving between jobs. A straightforward kit for repeated workshop use where accurate fault finding matters.
