1970 4020 Diesel: leaking diesel where throttle rod enters top of pump. still runs ok, just leaking! Would I be able to pull top part and replace O ring or something to stop leak or is this major trouble. thanks. JDM

yes you can replace the throttle shaft seals. people do it all the time on 6.2L GM diesels which use stanadyne pumps which are the same as roosa master pumps. but on a 4020 i think you have to remove the pump to get at the throttle seals.
