    Gauge: Sending unit & Size

    On a 92 k1500 what water temp sending unit is used for the gauge? The one on the side of the block or the one next to the t-stat housing?
    If you know the size so i know what to tap that would be great too.

    Also just double checking the oil pressure sending unit from the 92 is 1/4" NPT correct?

    my oil one was 1/8th NPT. It had the small OP fitting. Buy the 1/4 and if its too big you can buy a reducer.
