Re: Newbie...oil pressure sending unit and misc...
I managed to find a sending unit that *seems* to be the right one. Of course the gauge did not work when I installed it. Upon more investigation, the voltage regulator (takes voltage down to 5 V) for the gauges (oil pressure, temperture, and gas) was not working. Even if I cannot find a OEM or aftermarket specifically for the Scout, I should be able to get one from Fry's or Radio Shack that will work for this application. In previous job, I was a computer technician, so electrical circuits are natural to me.
Thank you for the post...I think I ended up with a sending unit from AMC 258" inline 6 (used to own one).
