Q: Will this fit the 6.7 engine

Do NOT buy this! Put one on my truck and it was junk. 5.9 cummins, ran horrible. Did not control pressure. Injectors sounded like the were coming apart and black smoke poured from my exhaust. I put the one I took off back on and it returned to normal operation. No problems since.

Q: Why is the nut on the top the stock one does not have that?

The white plastic anti-dirt cap? It's not a Nut. Thanks
