Do I need special tools to rebuild a DPA pump?

Yes, DPA pump rebuild requires specialized tools including bench fixtures, timing equipment, and pressure gauges. Professional rebuild experience is recommended.

Can I rebuild the pump while it's still on the engine?

No, DPA pumps must be removed from the engine and rebuilt on a bench. Proper timing and calibration require test equipment not available on-vehicle.
