Good info ???
I had a "DIESEL MECANIC" from for the told me that 7.3 don't have injector cup, that the injectors just sit in the head.
That was a conversation by phone.... i hang up ???
Maybe you shouldn't have hung up, you might have learned something. 7.3IDI's don't have injector cups.
Decades ago, first year Chevys got the Duramax or last year they had the GM diesel, my wife insisted on going by the Chevy dealer for their end of the year sale just to look. I was looking at a new (next year's) Chevy diesel and a salesman said they had a Cummins engine this year. I asked if I could see it, he raised the hood and I said that's sure not a Cummins due to what's stamped on the valve covers. He ran and got the sales manager and showed him and they both said they'd got info that it would be a Cummins, so you never know.
