Hmmm.... Why not ask the seller???
Pensacola diesel remans, not Bosch.
What makes you say that they are Pensacola Diesel?
Why would you buy injectors you dont know the history of, esp for an LB7? IMO, you're just asking for trouble.
I'll explain.......first of all, I bought them basically for core price. $400 for 4 "new" "reman" whatever..... injectors, that's core pricing. So I figured I could either trade them in and do my truck 1 side at a time or find some history on them to see if they are good or not. And if they turned out to be good, then use them and have one hell of a bargain........either way, I'm not out any money!
Anything but factory rebuilds is a crap shoot. Come to socal I'll fix you up $2350 factory parts and labor!
