How to tell?

[86.9]

I can't say for sure. The truck only has 83,000 miles on it. The pump and injectors were replaced in the late 90's although not at the same time. The pump failed and the injectors were replaced later in an attempt to get better performance out of it. I didn't notice anything after changing them. The truck sat alot until the last year and a half when it became my daily driver. I am going to guess the truck had around 50,000 on it when the pump and injectors were done.

Are you positive that is original miles?

My dad bought it new so I am sure. He didn't drive it much either, mainly to pull the fifth wheel.

I have a 1990 7.3l motor that is sitting in my shop (it through a rod) Just taking a quick peek at the injectors; all I could see in regards to any stamping was the letter ''D''

What injectors are these? Im betting they are original
