I know you can't just re-plumb a temp gauge because the line is filled with either. What about an oil pressure gauge? If the line is cut can you just replace the line or is it filled with some sort of gas also.

Replace the line. No harm no foul!

Just replace the line. If the gauge is good it will work fine.

I believe you will need compression rings to go with the new line.

You probably have enough slack in your line to cut end off, and put on a new compression ring which you can get at Ace Hardware.

Gord&Fran In the olden days they had a one time nut with the ferrel made on it,you'd just cut it off and use a new one. Later big trucks had a line with a "cushion coil" rolled in it using modern ferrels.

dgrinnen Can use copper,steel or plastic most old bolters would probably use steel if they can find it. 1/8 th on old ones it's not real responsive but was stock on 50's AD trucks.Used to find a big truck junked to get the line with a factory coil on it to pad the gauge.

The line and gauge are (eventually) full of oil. So you need to make sure the connection at the gauge doesn't leak or you'll get oil on your shoes. New fittings and ferrules would be a good thing.
Get enough line to put a coil (3-4 inches in diameter and about 2 full coils) in it just outside the firewall. The main purpose of that coil is to give the line flexibility from vibration between engine and firewall (as well as act as a snubber to keep the gauge needle from bouncing too much.)

Thanks for all the feedback. My current gauge has the line completely removed. I will be a new line from the gauge all the way to the engine connection. Is there any value in trying to pre-fill the line with oil?

No need to fill the line with oil. Pressure is pressure, whether it's oil or air.

dgrinnen Be sure your gauge connection is oil tight,a leak under the dash creates a tremendous mess you can't get to to clean it up . Also I think on the gauge you'll need a nut with the ferrel made on it. Been a while since I fought that,hopefully when you took one loose it wouldn't be too far gone to re-use. Back in the day you usually had new nuts available,now the kid will just look at you !!
