oil pressure line

The original metal oil pressure line broke off in my 73 build. Has anyone replaced it with the plastic lines?

Will it bolt onto the back of the original gauge?

You can take the broken piece and remove from the nut carefully with a small punch.
You can cut/file the old line clean, slide the nut on and recrimp when you tighten.
Assuming you have enough line remaining.
I've been successful on the engine side.

It's been a long time since I had one of these apart. Lots more available since I took my notes. Better than my meager post here. 
When I googled Weatherhead 6100X2, the part # in my notes, one of the first few hits was Ray Mcavoys' page on these fittings... http://rmcavoy.freeshell.org/Oil_pressure_gauge.html

First off.  DO NOT USE NYLON/PLASTIC LINE.  Replace the 1/8" steel tube with Copper.  A 6' coil of suitable 1/8" copper tube is Autometer part # AMG-3224.  Not the only one but easy to find.
As Ray notes it's a good idea to make a coil in the line between the engine and firewall to take up flex somewhere other than the fitting end...  Just like the coils in the Brake Master to Combination valve lines.
Replacement compression nuts or "threaded sleeves" are Eaton Weatherhead 6100X2

Thanks for the info on the Weatherhead fittings. I bought 10 of them. The only bad thing was that it cost twice as much to ship.
