What causes a fuel injection pump to leak?
The Red arrow is one area that I suspect it may be leaking from (as well as the #15 gasket). The Blue arrow is where the Diesel collects before it drips down on to the ground. It appears to me if leak is caused by failed o-ring (key 5 T28582) that engine oil not diesel fuel would be leaking.
How can I tell if my fuel injector is leaking?
Once you notice any injector that is spraying excess fuel, it is an indication that the said injector is leaking. For a clear visual presentation, watch this video. Just like checking for fuel leaking injector, you have to clearly look at the injector areas to see if there is any leak.
What to do if fuel pump fuse is leaking?
Remove the fuel pump fuse, wrap the leaking injector with a shop towel to soak up the gasoline and start the car. Allow the car to run until it stalls. This step relieves the fuel pressure in the fuel rail and the rail can safely be removed. Disconnect the injector wiring harness and remove the fuel rail bolts that hold the rail in place.
When to replace the seal on the fuel pump?

Why do I have a problem with my fuel injection pump?
Fuel injection problems, therefore, are one of the most pressing engine issues to deal with. Whether you’ve experienced fuel injector failure or not, it helps to understand the fuel injector pump, how it relates to engine performance, and also how diesel fuel injection pumps differ from traditional gasoline-powered units.
What causes a diesel fuel pump to back up?
A clean diesel fuel pump injector is a happy diesel fuel pump injector. Over time, residue can build up in the fuel system, and enough gunk, grime and grease can clog up the entire fuel injector pump. The spray tip (where the fuel leaves the injector and enters the combustion chamber) is particularly prone to “backing up,” so to speak.
