I hope I was clear on that last reply. I went out and got a bunch of this stuff awhile back. I am going to add a mechanical oil pressure gauge in my 'burb and still run the factory dash guage. I bought copper tubing, compression fittings with ferrules (the little ring) and even found the combo NPT to compression adaptors. You mite find the stuff at Home Depot in the plumbing dept.

I picked up the copper line because the gauge kits nowadays come with some type of plastic line. I'd rather have the copper as Ive seen it pretty beat up and not leaking. Worth the hassle of trying to thread it thru the firewall IMO. .....hope you get it straight.
