FAQ

1. What is the difference between the PT14 and PT78 plunger models?

The PT14 and PT78 are different model designations within the A Series plunger range. They typically differ in plunger diameter and overall length to match specific pump elements. You must check your pump’s part number (e.g., 134178-5220) or measure the existing plunger to select the correct model. The PT78 is the model number for the specific OE reference 134178-5220 provided.

2. Can this plunger be installed in any diesel engine?

No. This plunger is specifically designed for A Series in-line injection pumps used in diesel cars and light-duty applications. It is not suitable for common rail systems, rotary pumps, or large industrial engines. Always confirm your pump type and model number before purchasing.

3. What maintenance is required after installing a new plunger?

After installation, it is critical to prime the fuel system to remove air. We recommend checking the pump timing and adjusting the fuel delivery as per the engine manufacturer’s specifications. The plunger is a wear item; regular inspection of the fuel filter and clean fuel supply will maximize its service life.
