Leaking injection pump

[bryancald]

OK, I searched the forums for posts relating to leaky injection pumps and couldn't find the same symptom. I have a N/A D24, it has progressively become harder to start (irregardless of temperature). It's now having a hard time idling, and has started to stall. This morning I popped the hood and noticed fuel leaking from the injection pump to block junction (I think). Is it possible that the injection pump is just loose, or is it more likely a seal issue? I recently started running B99 biodiesel with the understanding that the pump seals were replaced shortly before I purchased the car a year ago. Are the pump bolts easy to access?

Thanks for your help!
