    Have a 4MG 3406b with a OR-6957 turbo. seems to have fuel turned to it.
    This truck had been sitting up for the last 6 years when I bought it this year.
    Had timing advance rebuilt, diaphram replaced, ran overhead.
    Pulled nozzles out, 7W7041 going to have them checked.

    Was wanting to know what nozzles would work best.
    Pull 80K +, Mostly flatland .I'm the only driver.

    Thanks Manley

    Arkansas Fuel injection can get you a better deal on CAT nozzles than CAT. I can’t remember the mans name that works the front since Jerry retired but he’s a jam up fella

    David that’s his name....sorry old age is catching up to me with names

    Got nozzles checked today, one was cracked, three were pretty bad shape, the other two passed the test.

    David fixed me up with a set. Real good fella to deal with! Thanks again wore out!!
