Help getting a oil pressure gauge installed

[OhmanSWE]

Hello!
I have a Cadillac deville 1966 where the previus owner engine swap to a 5.7L vortec 1997.
I would like to install a oil pressure gauge, where can i install it and how?
I have read it could be behind the oil filter where i should be able to screw in a nipple and get the tube from the gauge installed there. Any one have any pictures or some tips how to install?.
Sorry for bad english im from sweden.
Great regards Pontus

Theres several spots you can tap into should have a 1/4 pipe plug threaded

If you go with a mechanical gauge, don't use the plastic (nylon) line that comes with the new gauge. Buy a copper line kit for it. All of the copper line kits should come with the correct 1/4 NPT fittings, too.

This company makes a nice adapter so that you have multiple ports to tap into. Use the location behind the distributor it's the easier of the 2 locations to install one of these. It's cool to see old American luxury land yachts being restored and enjoyed in your country!

429 Caddys are hard to source parts for in the USA. I hate to think how expensive it would be in Sweden.

Good luck.
