Oil pressure sending unit location and more
So today I bought a new sending unit to eliminate my red "engine" light. I made sure to order the one for the warning light, not the gauge. According to the manual online at Autozone this is located just to the left (or in front of) the oil filter. I spent at least 3 hours trying to get the old one off, unsuccessfully. I tried sockets, vise grips, etc. No socket fit. 1" was too small, 1 1/16 too big. I destroyed the old sending unit. Then when I started the engine to see if the old one leaked after all my destruction, the red "engine" light was still on and the gauge didn't register, telling me that either the wires are plugged into the wrong oil sending units, or I was working on the wrong one the whole time, thanks to the Autozone online manual. So I have several questions:
1. where the heck is the second sending unit (the one not to the left of the oil filter, looking from the driver's well)?
2. which one is which (gauge and warning light)?
3. How the frak do you get the damn thing off without a 1 1/32" socket (which I've never seen)?
Help would be GREATLY appreciated!
BTW, it's an 87 w/302
