Both are the same but 0274 has a different internal relief valve, supports higher pressure.If you are running a lot of boost then it would be a better choice

This...

The higher pressure relief valve is especially important when starting with higher rail pressures (like on the 2.7T).. Even at just 22 psi of boost you're going to have the normal pump start to dump fuel pressure (80 psi rail).

more details on 267 dumping fuel at around 80psi here:

Same pump but with factory higher set valve.
