Yes I know the Classic Parts sending unit is NOT AC Delco it just does not have any plastic parts showing.
I would rather not have a sending unit with any plastic if possible.

What little I have found says the last AC Delco sending unit for my truck was FLS1098 or #19180458. This sender uses plastic parts and a flat ceramic resistor wafer that uses surface resistance material not wire. I already have one of these sending units and I am not impressed.

The previous part number appears to be #25000610 and it looks like the original sending unit with no plastic showing but these are rare.
