When you make your line up for the mech. gauage I would make it out of copper line instead of plastic, I've seen the plastic ones break,no fun to see smoke coming from under the hood and freeking out when you look at the gauages and see no oil pressure

i couldnt agree more.. go to your local home improvement store and get a refrigerator ice maker water line tube and two compression fittings.
or if you want to convert to electric I have a gauge ill send you for free..
