Oil Pressure Gauge (Page 2/2) theogre JUN 04, 10:31 AM Old style plug is careful straight pull. If outer plastic of plug shrinks or hard can be hard to remove. Is has a "bump" area to "lock" them sim to Coolant hose w/ bumps in case their clamps get loose. "88" is standard Metripack w/ locking ear. The ears often break off over time like many MAP sensors but seal between sections often keeps them in unless something is pulling in the wires. greenturnedblue JUN 04, 01:01 PM If it's a non AC car the sender will be screwed into the block right above the oil filter. It is first screwed into a small brass adapter which is then screwed into the block. In that case unplug the sender from its plug and you can unscrew the entire 'sender+adapter' Rhodesia1977 JUN 04, 02:03 PM It's an AC but that's good to know. Thanks.
