Now I'm really baffled.
Got a loop in the line at the back oil line.
Front line goes up and over pump, so that one definitely holds oil in the filter. Tightened up all the fittings again. I was able to tighten them up more for some reason.
I started it up and now only 3 days and it lost prime.
Turned off ignition and turned it on and it took about 20 seconds to get oil pressure.
I did use the oil accumulator and got 25 psi shot into the motor.
But oil pressure did not go up quick enough for my liking.
Wondering if they make a 1 way check valve for the bottom oil line?
Going to try again tomorrow and if I lose prime again I'm going to change out the oil filter back to my trusty WIX.
Sammy, mine does the same with the Wix and Mobil1 filters, and mine does what yours does, exactly. I am now thinking the filter is full, but the oil in the pump drains back into the engine and loses its prime. In the summer heat, I sometimes get pressure right away. I am thinking if there is a way to prime the engine with the accumulator off of the front of the oil pump...maybe that would work??? Mark Mark. my oil accumulator sandwich is between the pump and oil filter. When I hit the switch, I'm sure that oil must go into the line I'm going to see if I can raise the rear oil line above the oil pump tomorrow, somehow. I might have to change a fitting or 2 to get the line up. I hate seeing no oil pressure for 20-25 seconds. Never had this problem before.

Anyone running thier motor without oil pressure for 15 to 25 seconds better look at your bearings. Mine were starting to smear bearing material. Your results may vary.

Sammy,
I looked at the Indy Billet oil pump today...the pump looks to be cast Iron (Indy part) and the cover is two piece. There is a cover bolted on the pump, then an adapter for the oil filter. On the top of the Oil filter adapter there is a single 1/4" pipe plug on the top. I will call Indy on Monday to find out if my accumulator could or should be plumbed into there???
Mark Yes that's where I had mine on. I wish I never switched from Indys pump setup. Never an issue. -10an line to the 1/4 port.

When I'm ready to turn off the motor, I rev up the engine to get maximum oil pressure, then turn off the switch. It will hold my75psi till I turn the switch back on to prime the engine.

You guys have mentioned the shape and angle of the feed line. Does mine look ok? I haven't really had any problems but it takes about 3 or 4 seconds to show oil pressure when I fire it up, but I don't know if that's just because of how long it takes the electric oil pressure gauge to react?
I have a habit of letting the motor turn over for about 5 seconds before hitting the ignition toggle switch just to get the oil moving but I don't know if that's good for a motor or not?
I've done this for many years with no problems but I'm always willing to learn.

The delay is probably the sender, that assuming your using a BB and your taking the pressure reading off of the back of the block, which has to fill all the oil passages up before making pressure   I wouldn't and don't spin the motor over on the starter any longer than it takes for the motor to fire, why do that I know, it is a old Chevy racer trick

Ok thanks Cab, that's about what I figured.
As far as spinning the motor for a few seconds before hitting the ignition, that's only for the first start of the day(or week), my theory has always been that it would get the oil moving for a few seconds before the motor is fired and spinning really fast, but if you guys think it's completely un-necessary I probably won't do it anymore.
Does the oil feed line look ok in my photo?

I dont.. you need a hump in that line to act as a trap.. right now your draining about 90% back of what you have  That's what my thought is as well. How fast do you think it takes for all the oil to drain out and lose prime. Mines very similar but mine has a little more of a hump. So far 2 days and I still have prime. Don't think 2 more days will have prime.

That would depend on the clearances.. mainly the pump and the oil level... I use to run a fairly tight radius on the hump to keep the air volume down to a minimum and try to keep the hump close to the pump(again less air volume)

I use a 45* fitting at the pump, and right angle at the pickup.. That is why I was asking if I would be better off to run the Accumulator to the fitting on top of the Indy filter adapter, instead of running an AN -6 hose to the back/top of the block. Thanks for any advice, Mark

Thanks for any advice, Mark I never ran a accumulator so I cant say to that,, all I know is you want a large volume of oil to dump quickly so you want a good size port... I bought a accumulator but never hooked it up

Thanks for any advice, Mark Minimum of -8an is recommended and I believe the back of the block is NOT advisable to use as a prelube.

Are you talking the oil pressure line supply port.. if you are thats a 1/8" and by the time you put a fitting in it that would be WAY to small

I dont.. you need a hump in that line to act as a trap.. right now your draining about 90% back of what you have Mike, I'll make a new line with a 45 degree fitting at the oil pump, that should give a small hump up there to keep oil in the pump. Sound correct?
