Hard starting and low power
A worn injection pump delivers less fuel at lower pressure: long cranking and weak power under load.
Smoke and uneven running
Uneven delivery between cylinders shows as smoke and rough running.
Fuel leaks
Leaks from the pump body or shaft seal mean it is time to replace it.
Fitting tips
Set the pump timing to the engine maker's figure, bleed the fuel system, and use clean fuel and new filters.

Yes, it is a direct replacement for the Delphi 9520A380G with the same fitting.
Often 5,000 to 10,000 hours with clean fluid, much less with dirt or air in the system. It is usually changed on condition, not by hours.
Leaks from the seal or weep hole, noise or whining, overheating, or falling pressure or flow under load.
Most failures come from contamination, cavitation from a restricted inlet, or running low on fluid. Check the inlet and the fluid before fitting the new fuel injection pump.
Clean them right back to metal and fit the new gasket or O-ring dry, unless the engine manual calls for sealant.
No. It is an aftermarket fuel injection pump made to replace the Delphi 9520A380G. It is not made by the original manufacturer; the number only shows what it replaces.
