ABSTRACT:
A probe and sump drain assembly (128) includes a fitting (136) secured to the wall of a sump (98) to which a probe housing 146 is threadedly engaged. The fitting is provided with a stepped bore having larger (142) and smaller (140) diameter portions. Seals (154, 156) carried on the housing (146) control fluid communication through passages (160, 162) communicated with the larger portion (142). A ring terminal assembly (170) provides an electrical connection with the fitting (136) and with a transversely projecting portion (166) of the probe (144) regardless of the angular orientation of the portion (166) of the probe (144).
