On dps website for the injection pump modification, It says its best to have a XX31 IP but the XX29 can be brought up to spec. Well, I have an extra injection pump and can't find the numbers he he talking about. Here are the specs.

DB2-4746 988

052192GMC 991584C91

These are the numbers in the same arangement as on the tag. Can anyone tell me if this is a 29 or 31. By guessing, since I can't find these numbers, its not. Also, Does anyone know if this is the 6.9 IP or 7.3 IP and around what years was. Just asking some a few of yall might know just from the numbers but I sure don't
Thanks

 

87 6.9 IP.

The 31 pump is the 5069 or 5070 for the turbo motor.

 

Just guess, but I think the GM 6.2 used a db2 pump, maybe it is for that?

 

Well, the pump levers are setup just like mine and on the passenger side. I think the GM ones linkages are on the drivers side. I THINK. I could just have a $45 paper weight!!!

 

That's correct, however AFAIK their pump rotates in the opposite direction compared to ours.
