    I want a 6 AN fiiting to fuel pump but don't know the seize.
    It looks like a CARTER fuel pump.
    npt ?
    3/8 ?
    1/4 ?

    I know its a reverseble flare but what seize/thread ?

    Almost always 1/4" npt. Judging by the nipple on the pump I am pretty sure that's the case here. 3/8" npt is huge for a fuel line. Like, feed a drag motor huge.

    Probably 5/16 inverted flare

    The fuel line itself would be 5/16" but aren't the threads in the pump 1/4" npt?

    I naturally assumed #2 below. You meant size ;)

    1. take hold of suddenly and forcibly.
      "she jumped up and seized his arm"
      synonyms: grab, grasp, snatch, take hold of, get one's hands on; More.
    2. (of a machine with moving parts or a moving part in a machine) become stuck or jammed.
      "the engine seized up after only three weeks"
