Have a local customer needing a D19 oil pump, and I don't have enough experience to understand why thee is a serial number break in the parts books. I only see a couple of nuts different at the 121675 break. I also cannot visually see any difference in the gas/diesel pumps, but I'm sure the diesel is running higher pressure?

Gas/diesel oil pressures settings should be the same.

So would the pump interchange?

Yes, should be the same. Some had a relief valve on the pump along with the one on block. Some only used the one on block. MACK
