Had DAP rebuild some injectors with 150 nozzles. I got the injectors in a trade that were supposed to be 200's. The numbers on the nozzle are DSLA 150 P 755, and a 77103 with 939 below. It's not a big deal, I was just curious if these were actually 200s. The notes said all 6 old nozzles were leaking anyway.

it is going to be very  hard to answer that question.  More ofter than not the numbsers do not related to an aftermarket size.

Figured as much. I was just curious. Regardless, I wasn't putting the injectors in my truck without them being gone thru first.
