Trouble with oil filter connections 48 DeSoto

[MarcDeSoto]

I am missing some of my oil filter tubes, so I'm wondering if I need to buy 3/16 brake line?  Also there's is a short rubber tube that goes on the line to the oil pressure gauge.  Where can I get that?

Brake lines work fine for the filter, I bought the rubber oil pressure hose from one of our major vendors, think it was AB.

   I just installed my second Wix 24755 bypass filter housing, with a NAPA 1320 spin-on filter. I was using a 1010 element that seemed to fit in my old housing, but the lid gasket was wrong, and the old housing gasket was sweating oil. I used Eaton inverted flare fitting numbers, 90 degree-402X3, 45 degree-352X3, straight 202X3, inverted flare plug 131X3. You won’t find a 10-27-10 elbow. My oil pressure gauge line comes from the rear fitting on the block, above the starter. I used Ni-Copp brake line sections. A 12” worked for my feed line and I had to cut and double flare a 20” line for the return line. My old flare tool, with cheap double flare buttons, got the job done but bent the center pin on the button. I changed the oil, and started, no leaks.  I ordered a Titan 51535 flare tool yesterday, to hopefully, get consistent double flares. The spin-on filter, might not be period correct, but you know it’s working, by design. No more searching for the correct filter or gasket from multiple manufacturers, and it’s cleaner.

I replaced all the lines and nipples with NiCopp tubing. Also replaced the elbows at the can, and the rubber connection to the oil pressure meter. I've only ever seen one of these things (mine), but I'm gonna bet that they all leak eventually around the seam at the bottom of the can. I ran a bead of JB weld around that, cured the leak.

Here are the fittings I installed for my bypass filter, some of this might be applicable for the Desoto installation. You can also see the new oil pressure hose. All these fittings were purchased at a local auto parts store, the tubing is pre-flared brake line.
