Does anyone know size the stock sender is? Im wondering if I need to get any extra adapters for the stock 2.3 block

Includes 1/8" NPT Sender.
Air-Core meter movement.
Includes 3/8"" NPT adapter/fitting.
Includes 1/2"" NPT adapter/fitting.
Instrument features brushed aluminum dial in silver finish with matching silver anodized bezel.

IIRC mine went right in where the old one was, no adapters required. BUT - it's been many years, like nine or so.
