After getting my engine on the run stand and letting it sit a few days between starts, it does seem that it takes 4-5 seconds before it picks up oil pressure so I decided to put in a check valve. Could you guys take a look and see if what I have mocked will work or do I need to take another approach. I thought I remember reading in my other post, that it was beneficial to have it laying horizontal, just worried about the two 90 degree bends.

I tried this way back but the one way valve I used must have been a restriction, I lost around 20 psi when priming with an electric drill. I removed it and never bothered trying anything else, just went to priming with a drill as part of the start procedure. Of course you may have a less restrictive valve but it's worth checking.
For info we are using a dual line, I only lose prime after 6 or so days, any time before that, the load is already on the drill. HTH's

With a check valve you should no longer have to worry about running the line over the pump. You could get away with a much shorter line running it down and under the pump. The check valve shouldn't care what angle its at.

Using the iron cover ... smart move !!!

I wonder if it is that pump combination with a stock cover causing your slow to get pressure

Why would that be the cause ?!?!?

Very good point on being able to able to use a shorter line. I actually have a shorter line with two 90 degree ends. I held it up against the pump and pan and I actually think it may work. It looks like it will have the check valve in a vertical position. If I can get the line to hug the block it should have enough room to where the crossmember isn’t an issue. I will probably try to mock it up tomorrow and post some pictures.

putting a loop in the hose fixes a prime problem

He doesn't have a prime problem. There is nothing abnormal from his video weeks ago. No engine picks up oil pressure with a tap of the key. Does the engine have oil pressure when running? yep. Is it normal yep. Good to go.

He'll probably cause a high rpm starvation problem, with all this bs and blow it up. Ain't no way I'm putting anything between my pump and its oil.

I have to agree with that.

My thoughts too. Maybe a dual line system would be fine, with double the volume capacity to start.

If this isn't a loop then please tell us what is !!

However with that said, even with a loop all the oil in the loop below that horizontal line will drain back into the pan - very easily and quickly when its hot. What little is left above the pump is all you have to prime with. Then that long loop as to fill up before you have continuous flow and pressure.

So while a loop is a good thing, you still want the feed line as short as possible. As for that check valve, its pretty fat - I doubt its very restrictive to normal flow.

I think what he meant by loop is a 360* loop. Then the oil will stay in the hose closer to the pump.

My point is all of this is nonsense. loops included, but they can't hurt. Stock internal set up has no loop and pump is in the same location.

Put an accumulator on it switch it on while you are cranking, problem solved. Doug

The problems come when the oil is thick, clearance in the pump may be too much, or the lines on the intake side are larger external, which provide a lot of dead air before oil is pulled into the pump gears . With a. Wide clearance like i found on my BRAND NEW milodon highvolume pump, even a high speed large drill had a very hard time pulling a prime. Once oul drains off the pump rotors too much leakage by the extra clearance caused my deal much grief. Two hours of hand sanding the aluminum pump body to reduce clearance may help. I sanded it down from .004 to .0017 clearance, which should help a great deal. I will reporrt back.

I have a hoop or loop, however everyone wants to word it on my dual external line pick with no issues. I also run a Accusump as a primer, or preluber.

I've used two in line oil filters in one of my old dual line Milidon external oil systems with no issue on lubrication on that motor I don't remember the micron rating of those filters, maybe 100+ micron
I had a small piece of the rear main seal holder pop off of it when I used to long of oil pan bolts and that small piece got suck up into the oil pump through the stock internal oil pickup and locked that pump up and broke the oil pump drive shaft off at the top of the oil pump drive rotor in the pump on the return road
Murphy loves messing with us stupid drag racers

I've seen pumps pick up chunks of block and never snap , and putting a filter in the suction line your crazy , What are you protecting with that? Lets see plug the filter destroy my whole engine? At least you stopped trash from getting in your pump.

Heck the factory will bypass the filter on the pressure side before hurting anything.
