If you have a gauge, the sender usually has a square between the "bell" and the threads. You can use an open end wrench there and just remove the unit. If you have a light, then yes there are a few different sized sockets made just for sender removal. Many aftermarket sending units have normal wrench pattern instead of the socket size to make them more user friendly.
You can usually get that type out using a pair of slip joint (waterpump) pliers, but if it does not come out using reasonable but not excessive force, get the socket. (if you distort or crush it the socket won't fit)
I have never heard of the coil wire thing and really see no benefit in doing that.
i do recommend that you put one wrap of teflon tape around the threads to prevent seepage and prevent binding in future removal. Don't go below the second thread though so it doesn't come loose and cover the orifice.

How do you determine the oil pump failed on a 3.5 SE


you need to check oil pressure. you need oil pressure gauge and you will need to remove the oil pressure sensor from the back of the engine, just above the oil drain plug. its a single wire connector. the sender is a special socket also. just heads up. remove the sensor and screw in the pressure gauge. run car and observe pressure reading. if pressure is low, then the back timing chain cover gasket is most likely blown out. have seen quite few with than gasket blown out and that will cause low oil pressure.

I need to change the fuel regular and O2 sensor in my 89 GMC tracker. I have the parts but am unsure where they're located. Is this an easy process?


ok 89 is a 1.6L 8v motor.

i suspect you mean REGULATOR as in Fuel pressure REGULATOR.

1: O2, see exhaust manifold ,remove o2 sensor with special tool.
2: put new one in its place and plug it in. done.
if tight use heat or penetrating oil spray.

3: FPREG. see Throttle body , looks like naked CARB?
its under the right side of air horn tube.
on the face of it (front) is the fpreg.

go to my web side and follow my fuel depresserization steps.
http://www.kick-fix.com/
then remove return line.
and unbolt it.
now put new one on.
and lightly tighten it,(alum. threads not too much)
put back hose and the special clamp.

done.
