I have my 2 oil gauges done and working, but I can not find a way to hook up my water temp gauge. The deal is, the AutoMeter sender is 1/8"NPT and the stock Nissan sender is M12X1.25. I can not find an adapter anywhere, also the stock Nissan sender does not have the right output to drive my guage correctly. Does anyone know where I could find an adapter, or has anyone here put a 1/8"NPT sender in their GA that wouldnt mind helping me out. Thanks

SXSENIS,

Go to my website(link bleow), there are some good pics of my oil sender setups. This is probly a lil more involved then what you may want to do, but to tap for a oil psi guage, just get a "T" and put it in the stock oil psi switch locatation. I belive the size is 1/8"NPT, then you psi sender will go in one port and the stock switch will go in another. If you would like, I may be able to send you some pics of a setup that would work. I was going to do that orginally, but I decided to go another route instead. If I can find the parts I had, Ill take a pic.

regarding your water temp connection you can use the drain plug on the block to make your sensor connection. just remove the drain plug and replace it with the sensor.

If I recall correctly the drain plug is 1/8.

chef,
Do you mean the drain on the front of the block, I looked at that yesterday and it looks bigger than 1/8". Anyway, I am goin to scour that engine tommorow to try and find some plug that is NPT, I have a few adapters, maybe I will get lucky.

I just remembered that you will have to use an adaptor. Autometer usually gives you adaptors so just use on of them and you should be fine. Yes it is the drain plug that is in the front.

chef,

Well I just went out and pulled the block drain plug, it appeared to be 1/4" npt, but my 1/4" npt adapter would not fit in it. I have another idea though. Last night while surfing the web, I found Greddy makes a coolant hose adapter. It a short piece of pipe with a sender hole built in. The idea is to cut out a section of radiatior hose, put the adapter in place, then screw in your sender..problem is I do not know what size sender the Greddy adpter is made for. Does anyone here know?? BTW I would be a little worried about using the block drain plug location because it is only about 2" away from the cat-con, them babies throw off some heat. Would that affect the sender reading?

You have a 99 Sentra, right, and the cat is close to where the plug is, I probably wouldn't put it there then. You could possibly try a 1/4npt elbow male/female and see it that would work but I think the greddy adaptor seems like a good idea.
