MD injector pump

My MD runs fine on both gas and diesel. However the injector pump reservoir will slowly fill with diesel while it is running. I know this is a common problem with these pumps. Is it possible to replace a seal somewhere in the pump to stop this from happening? Where is the seal? Does anyone know the part number/CR number?
 
the little transfer pump seals are leaking diesel into the main pump. need to remove the transfer pump and replace seals. this is the little pump on back end of injection pump.
 
It's as rusted says. I think the seal is still available from IH. The new one is two seals pressed into a sleeve. When you get the lift pump apart, examine the bushings for wear and see if the pump teeth are rubbing on the housing. On my 400D I had to replace the bushings too.
