i just bought this autometer gauge off ebay. and when i go it, it had this huge AN fitting on the end. now most gauges i have installed on a 350 block use a 1/2" npt nut that screws into the head and then uses a 3/8" npt sealing nut to hold the sending unit in. can someone tell from these pics if i can use this set up, or if i can take this AN fittin off somehow to use the more traditional set up.

By the looks of things that isn't a stock autometer temp sending unit....

they're pretty cheap though.

how do you change these out?

They are real simple - two wires. One goes to engine ground and the other to the gauge itself. Depending on the gauge, you'll have to get the proper sending unit for it. A local shop can help, or you can check/ask Autometer. Jegs has a bunch(http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=3813&prmenbr=361) and Autometer's list is at http://www.autometer.com/hp/2003_catalog/accessories/86.html

this is a mechanical gauge tho....not electrical.

You can't change the mechanical guages,ther is a steel capilary under the plastic coating.Looks like you just need the proper SAE to AN adapter to make it work.Look through the Autometer site I bet you find it.

BTW,I didn't know they where making them like that.What is the part number?Might have to change mine.LOL

i didnt think you could change the mechanicals. the part number on this is 4331...same part number as any other 2 1/16" ultra lite mechanical water temp gauge. i emailed the guy. he said he had it run into his radiator, thats why its like that. i might end up sending it back to him.

It looks like you need a #10 or 12 AN to 1/2'' NPT to make it work.If you've got a decent speed shop nearby take it there and find the adapter that fits.I think the AN connection will look better then the others do.
