Help with 1964 4000 injector pump

I have what I believe to be a 1964 ford 4000 select o speed and the injector pump was seeping diesel into the oil so I remove the pump and began looking for a seal kit for it but have had no luck at all because a someone long ago removed the model number from the pump. Does anyone know which pump would have been used on a 1964 ford 4000 select o speed ???
 
It's a RoosaMaster (now Stanadyne) DBGVCC429-???. There are several possibilities for the 3 ? marks and they describe the advance mechanism. A gasket kit sells for about $30 but you will need to know which style of advance mechanism your pump has in order to get the correct kit.
 
Fuel in crankcase can also be the injector return line as it is under the valve cover, if pump shaft seals look OK the line and banjo bolts may need service. Your pump should be the late style with built in advance. Early pumps had a bolt on advance block. Just resealed an early one, but don't see them too often.
 
i believe it has the bolt on automatic advance block what would that make the last few numbers?
i would include pics but it wont let me upload them

if it is the return line how might i fix that?does the pump still need to be resealed?

found this pic on here this is the same pump i have.

Your tractor should have the late style with advance built into the housing. Bolt on was used on early diesels, unless someone replaced the pump with an early one. Valve cover must be removed to get at the return line across top of injectors. Most tractors I do the pump first, as owners want to leave the top alone if possible. Injector inlet tube gaskets can erode and leak also. That shows up on the injector poptester.
 
Who sells the seal kits for the earlier pumps? Can't seem to find one on ebay that has the oval shaped seals needed for the advance.
