Most of my Motor Guards are converted M 30 compressed air filters. The last one I did all I did was remove the white seals and put a 2 1/2 inch OD flat washer in the bottom for a core seal. Then put a 1/16 inch orifice at the inlet. The filters dont need a center tube. The Australian Jackmaster Classic does fine without a center tube. I prefer the orifice at the inlet. On the Pontiac I drilled out the orifice and used a Perma Cool universal 189 oil cooler sandwich adapter. The Jackmaster is mounted high. I have a air tank valve in the top. With the oil still hot I let air into the filter. Probably loosening the center bolt does the same thing. If air cant get into the filter the oil cant get out. If you dont want to deal with the other filters the Jackmaster is hard to beat. I dont care for the Frantz design. The others I like.The Flat head Ford V8 canister filter is set up for a 4 1/2 inch Scott 1000. I have half a roll of VIVA paper towels in it now. Use a sharp knife to cut them. A saw makes a mess.

Occasionally the coating will fail on the Motor Guard compressed air filters. The old Motor Guard lube oil filters had no coating.
Frantz is the only filter that depends on the fit between the center tube and the tp core. Some filters dont even have a center tube. All the Australian Jackmaster Classic has is a seal at the bottom. The Gulf Coast junior has a center tube but it is 1 3/8. All it is for is to remove the used tp. The bottom seal around the tp core is all that counts. I wasted too much time machining a center tube to fit the core. Push the tp core down against the bottom seal and put on the top. Its better to have the orifice in the inlet. If the seal is too small make it bigger. With the old Motor Guards that filter from the bottom up make a spacer for the bottom that pushes up on the core when you tighten the tee handle if you dont have 4 1/2 inch paper.I see you have had good results with adding an extra core, so I peeled off the shrink tube today, I cut off one paper towel core at 4 1/2 inches, found a 4 inch 1-1/2" tp core and it all fit inside the Kirkland core, I have found the Kirkland paper, when trying it before would pinch in the gasket at 4-1/4, so I used 3 sheets of Scott blue shop rolls cut to size, start and end affixed with a bit of Elmer's white glue, the blue shop towel stretches a good bit, just don't stretch it too much when you get to the sheet serrations. This roll is now round! lol, it's 4-1/4" in diameter with no gasket pinch at all! Should make an excellent atf element.
