OK
I hate to say this but I need to get in gear and get this stuff in.. Time is starting to catch up, and 3 months isnt that long really...
I plan to run a oil accumulator. I have NOT run one in the past. Im looking at the Canton's cause the match my paint LOL..

I would really like a electric valve control. I know some of these from what I understand doesn't open fast, and for pre-oiling only...Well I don't want that kind and I know to watch out when buying.
So right now Im looking at the 20-25 LBS electric valves style? Should I choose a diff one? At least a two quart version maybe three?
Also
How did you plumb these into your oil supply?
I have duel line system that uses a spin on filter. I was thinking there was a sandwich filter adapter available. It would be the easiest to plumb, I plan to mount the accumulator in front of the radiator, so a short line through the rad support down low will keep everything neat and uncluttered.
So if anyone here uses the manual valve, how do you like it?
If anyone has a part number on a adapter that would be great..I dont know if the oil cooler adapters will work or not?
This block has a oil port near the front of the block, but I am using it for one of the duel line system ports. I dont know how well this would work plumbing it to one of the oil galleys in the back of the block...Not to mention the clutter of having a probably a minimal -8AN line and probably needs a -10 really.

I have a Master Lube I have it plumed in on the outer cover of the oil pump where the line from the oil pan hooks up.I have it going in on the top side of pump.I think the oil pump is better than on the back of block.I have the tank mounted on the deflecter plate(back of seat).

I run a Moroso 3 qt accumulator with Moroso's electric solenoid valve, Indy billet pump cover with spin on filter adapter, to a single swinging pick up.
I have the valve on a 3 position switch. 0N/OFF/ON momentary. I flip the momentary on to prime engine and flip the switch to "on" before I stage the car.
While the switch is in the off position and the car is running, the engine will pressurize the accumulator to the highest oil pressure the engine sees. Then it is ready to prime the next start up.
I have the line plumbed into the filter adapter on the Indy pump cover.
I really like the priming aspect of it.

I am installing a canton 3 qt this week using the electric valve with the 20-25 psi switch I am pluming it into my remote filter.

I have a milodon remote filter cover plate set up. The 3qt.accusump is plumbed with a #8 line and tee's in where the out going filter line goes into the pump/block . I have the electric valve that will fluctuate with the pressure so it is open when the ignition switch is on. I don't know why someone would want to wait until their oil pressure dropped to 20-25 lbs before the valve would open. But thats me. Mine is mounted on the front frame stiffening pipe. electric valves can be bought off e-bay from valve venders for a fraction of what canton or moroso sell theirs for. Just make sure it's sized correctly and rated for temp and oil.

OK
the duel line system I am running uses this fitting on the block to provide on of the lines to the swinging pickup in the pan. (other is coming from the pump cover..
Anyways
Can I just add a T here? one still going to the swinging pickup as before, but the other going to the accumulator?

Like mine, I believe that port supplies the oil to the pump. If by chance your pump failed. the oil from the accumilator would seek the easiest path and that would be back to the pan. I'm going to use a similar remote filter as I have now on my hemi.

Like stated above using fitting will most likely result in oil just going to the pan period. Use the one on the back of the block, easy way that works. Or use the filter housing if going remote. I use the filter mount on the B1 on my Hemi I went with the nack of the block.

We use Moroso 3 qt with electric selinoids.Mine and others are plumbed into the fitting on the Indy cover plate and feeds the block.Don's and Pap Ross'is plumbed to their remote oil filter housing.

I have mine plumbed into the remote oil filter as well. I actually mounted mine in the windshield washer well. Its a tight squeeze but it fits and you don't even know it is there unless you notice the hose coming through the firewall.

Can someone post a photo of where it should be plumbed on the back of the block?

Is this a oil galley feed? Sure looks like it. And looks like it goes right to the cam,and mains in a hurry?

I looked at that port on my block but didn't investigate where it went. Put some air to it and let us know. There should be 2 tapped holes at the top rear of the block for the other oil feeds.

Is there enough meat on the rear 2 oil ports to tap one larger for the Accusump feed line??I just don't see that little orifice being able to flow enough oil to save my junk in the event of oil pump failure
