I installed my new DD2's about a week ago, thinking I was replacing some old stock injectors.

Well, I've since found out they weren't stock, but I am trying to find out for sure what they were.

I have been told they were/are marine 300's, but I've never heard of a 300....370 & 330, but not 300.

The number on the nozzle was 6816....does that tell ya anything ??

or is there a sight I can go to to determine what they were/are ?

At this point, I am about ready to take the new ones out and put the old ones back in...save some money, and not lose power.

 

The marine 300 and rv275 are the same injector.
