    That pump (7n4369) was used on a 92U prefix for truck engines, for what it's worth. I am not sure if all A's were 92U or not.

    From my research the 92u was made later in 1973 the first ones had the prefix 8sb. The truck that I have is a 1973 Peterbilt 359

    Interesting. I had an 83 A model, and I though it was a 92U as well. Maybe not...... that was quite awhile ago.

    It would have been, 92U was used right up until the roll over to the 7FB B model.
