The 12a and Aftermarket Gauges

striegels6 · 06-10-2010, 06:40 PM

I am looking to add Autometer gauges ( Temperature and Oil Pressure ) to a 84-85 12a. I cannot find any adapters that will work. The factory Oil Pressure port is a 10mm fine thread and the temp sensor port right next to the oil pressure port is way to small for the Autometer water temp sensor. Any suggestions are welcome. Part #'s would be great. I also need to hook up an electric fan. Once again Painless has the right switch but I cant find the right adapter to put the switch in the back of the water pump housing. Thanks for reading>

The oil pressure port is actually a BSPT thread pitch. Autometer has an adapter for it. Or you can make you own like I did. For the coolant, take off the water pump housing and tap it next to the other sensor. Or go the cheap way and get an adapter that goes in the coolant hose.
