I'm leaking diesel out of the ksb at he timing shim, I've had it off and back on twice. The o rings are oriented correctly and there in perfect shape. I've tightened it down several times and it still drips.... So what am I missing????

 

on the opposite side of the pump there is a cover plate that has the same oring as the ksb and it can leak. unfortunalty you have to remove the pump to replace that. check to see if its coming from the back or if it really is the ksb

 

I'll check it out when it warms up, -25 today without the wind chill,,

Thanks
