Oil filter questions

[fireguyfire]

I’ve got the flathead 6 from my 1940 1/2 ton back together this weekend, and painted. A bunch of engine accessories were missing from my seized engine when I bought the truck, including the oil filter cannister.

I was able to source a cannister filter that came off of a farm truck locally, and it is now time to clean it up, repaint it install it.

I will need to make new supply lines for it, but being that it didn’t come off of my engine I need some help in making sure I route the lines correctly. 
 

Im assuming that the pine that goes to the highest point of the canister is the input line, and the line that goes out the bottom is the return line; is that correct?

I also have a weird brass stub at the bottom which I am assuming is a drain.

 

Can someone set me straight on where the line originates on the engine that goes to the top of the canister, and where the line that comes out of the bottom tied back into the engine?

photos would be great, as I definitely don’t want to get this wrong and have an oil supply issue.

Any help would be appreciated!

There are 2 brass fittings in my lock that I’m assuming are for the filter lines to connect to; 1 is at the top of the oil pressure relief valve housing, and the other is a couple of inches directly above that in the side of the block. 
Im thinking the fitting in the top of the pressure relief valve housing could be the supply line to the filter, and the fitting just above that in the side of the block is the return?

Which way to plumb the filter canister depends on the manufacturer. Some input from the upper area and return out the bottom. Others feed in the bottom and return out near the top. See if you can find markings near the ports to identify which is IN and OUT. If you strike out there you may need to study the design to figure out how to plumb it and which filter element to use. Regardless of all of that, here are a couple of pictures of my engine to show the connections at the block and filter canister. Mine is a Deluxe Filter and it feeds IN at the bottom connection and returns from the upper one.

Remove the oil line fittings from the canister and look for the inlet flow restrictor to verify.

So just wanted to confirm JB; I have a restricted flow fitting on the bottom of my canister and a full flow on the top, which would mean the bottom is the inlet, correct?

I guess that does expose more filter element to the dirty oil.

I was trying to think, but nothing happened
