Oil/fuel leak

[Jman2109]

Hi everyone,
Looking for some help with our L1501 Kubota.
When running the Kubota we have an oil/fuel coming from the side of the injector pump and was wondering what could be causing this?
Please see the pictures of this issue!
Any help on this matter would be greatly appreciated.

It could also be hydraulic fluid.

You will need to get a good sample because you could have all three leaking from there and will need to know which one it really is.
