Hey guys I was wrenching on the jepp today and nothing good happened. The plan was to go in and remove the oil pressure light switch in favor of the oil pressure sending unit I have for the gauge to read properly. As I was trying to take the old one out *SNAP* the 90° brass fitting snapped at the block. I am trying to figure out what to do. I have tried an extractor bit but the drill doesnt fit the the space and the engine mount is in the way. I will post up pics soon

Hey guys I am New here i am now the proud owner of a 1990 4.0l renix thanks to the other forums regarding this, I am 95% complete. I am in the process of swapping out my idiot gauges for a full panel, i have only one issue so far and that is the part number for coolant temperature sending unit. I bought one from autozone its part number is tu108, however i do not know if that is for an idiot switch or for the temperature gauge, if someone has a part number it would be awesome. thanks Dis i have almost every major auto part store near by i prefer, oreillys or autozone(only bc they had it in stock)

Dropped the tank on my 91 to replace the tank vents which were leaking, solved that problem. The fuel gauge hasn't worked correctly since I've owned it. The gauge reading was floating from empty to about 1/3 tank regardless of the actual amount of fuel in the tank, but the low fuel light would come on when it actually got close to empty. While I had the tank out I checked the sending unit output and had 113-114 ohms with float down (empty) and 7-8 ohms with the float up (full) at the tank side connector. This is close to spec and the error may be from the Harbor Freight meter. I poured in about 10 gallons of gas and re-checked the reading at the tank side connector - 42-43 ohms. Cleaned the connectors as well as I could, plugged them back together, checked the gauge and it read about 1/3 tank. I'm thinking with a range of 110 empty to 3 full I should be seeing at or over 1/2 tank on the gauge. Tried to back probe the harness side of the connector but couldn't get a reading so I shaved off a little insulation and checked the ohm reading - 31-32 ohms. Losing about 10 ohms across the connector. At that ohms I should be indicating an even fuller tank. Insulated the wires I had shaved, buttoned everything back up, drove to the gas station and filled the tank. The gauge floated up to a little over 1/2 tank and floats between that and near empty as I drive around. I know I will need to check the wiring continuity and clean any additional connectors, but I'm wondering what else I may be missing. AFAIK, this is the original cluster. Should there be a ground strap/wire between the tank and the unibody? Should the 91 have a ground wire from the dash to the unibody like the Renix MJs? I can't spot one. I'm wondering if this could be a grounding issue as the voltmeter also doesn't work. Everything else on the truck works correctly. Any suggestions?
