Top pic is the original filter system. The second is where I have the gauge, pulling from where the No.2 main is. I’ll get pictures of how I have the filter now. But all it is, is a spin on filter, I’m running the line to the filter from the top hole and the return to the bottom hole where to original filter mounted.

Chrysler flathead guys…I need some help. Here in the story for reference. Swapping a 251 into my M37. I found a bad main bearing and was able to source new bearings of the same size. Crank was in good shape and measurements were good. Put in new main bearings and reassembled. I needed a military oil pump as I am running military distributor. I primed the pump out of the engine and put it back in. I then reassembled the whole engine and cranked the engine with no power to the distributor and got oil pressure to my mechanical gauge. I then added power to the distributor and the engine fired right up. No oil pressure. I then removed the supply line to my remote oil filter (I have a full flow filter) and cranked with no power and oil flowed out. I put oil filter back on, cranked the engine with no power and got 20 pounds of pressure by cranking for a few seconds. I then started the engine and you can see the oil in pressure gauge line and the oil sucks back into the engine and no oil pressure. I put new gauge on same as above. I took the oil filter off the filter housing and started engine. Oil came out of both holes. maybe my engine is missing a plug in the oil galley?? Anybody have any thoughts.
