Duetz injection pump leak

[Fixastuff]

I have this slow leak at the top of one of the injection pumps on a Duetz 2011 series engine. They are motorpal pumps not bosch. The engine manual only shows replacing the pump with no parts diagram of the internals. The engine is running great but I want to fix the leak before it gets worse. Does anyone know if this can be fixed without replacing the entire pump and without having to mess w
ith injector timing and shims. Both of which require a couple special tools.

Thanks!
