Rd28t injector pump leak

[mad66]

I have a small leak in my injector pump, seems to be coming from underneath on the engine side of the pump mid towards the rear of pump. it is only a drip every 3 to 4 seconds at about 2000 rpm. just wondering if anyone knows where it could be leaking from. I haven't been able to get in there properly to have a good look but I think it is coming drom somewhere in the red .

I think I might have got my leak location wrong. It appears to be coming from the right side lol. I will check it out better tomorrow. any good tips on finding diesel leaks?

Have a good look at the spindle that is in the topping the throne lever on it or the top plate seal
