Rawze.com: Rawze's ISX Technical Discussion and more

Recently I’m getting a message saying “ fuel filter restriction code 16”.
I replaced both fuel filter and water separator right after I saw the message first time. I don’t know the reason this message is showing up again.
It’s a Peterbilt 579 and Cummins ISX .

What year truck/engine?

will it pass a rail leak-down test?

It is 2015 Peterbilt 579

Haven’t checked it for rail leak yet
