If you want "true" oil pressure, there's a 3/8" NPT plug o nthe oil pump itself, it's a hex head plug. Remove it and use a 3/8" NPT adapter and put your sender in there. That'll give you the true pressure that the pump is putting out.

Sorry, when I said "true" pressure that's what the pump is putting out. I don't agree with taking the oil pressure at the filter, I take mine from the proper nipple o nthe block itself, cause as mentioned this is what the engine as a whole is seeing. Cams, etc.
^^^ Not arguing; I just found out something I didn't know. The only reason I'm going to use a sandwich plate is because I have oil pressure and temperature sending units as well as a turbo feed line and I really don't want all those tee'd off the same source. I want to get the pressure sender out of line with the feed line because oil moving past the pressure sender will cause lower pressure readings. My other option is to tee in the pressure sender where the current feed line is (just before the stock pressure sender) and then relocate the feed line to the sandwich plate.

Personally if you have to choose, I'd run the turbo feed line off the sandwich plate, and take your pressure reading from the port near the top of the block.
Hey Tom. I've been away for quite a while, but you might remember me. I'm the guy who bought a spare race motor from Fountain Motorsports a couple of years back. Yes, it's still in the crate, lol, because I haven't felt compelled to install it with my original motor running so well (101k miles now and compression at 189-194 psi). Nevertheless, I'm now progressing toward getting that motor ready to go and I think this discussion will apply to my situation. I remember talking with you once about the oil pump installed on that motor. Apparently it was modified for race duty and was set up to use an external pressure regulator, so we talked about me getting a stock pump from you. Although I don't race, after reading your info and understanding the stock pump's limitations, I think I might rather have mine set up like you've described. I'm wondering now if I don't already have one of these coated pumps, since everything else in this motor was coated by Swain Tech. Would you remember if Fountain was doing this with the oil pumps back then? I guess I could always disassemble it to find out.
I'm also concerned now about the oil pan on that motor. It's a custom gated pan, and looks to be the same design as what you're running. Someone mentioned leaking at the welds... aaack! Any chance I have one that won't leak?
Anyway, glad to see you're still around and doing cool stuff for the community.

You will need oil relocation sandwich plate setup you can find on ebay doc can supply you with pressure regulating valve 10an fittings at auto parts Russell fittings worked out great for me and I can supply you with -10an braided bought a box of 25 feet only needed about 10 foot also dont forget return line fitting from PRV into oil pan have someone weld a 10an fitting into pan at top.
Please.
I am considering how to route line to include this ext PRV and the thermostat activated oil cooler.
I guess it would go like this:
Filter spin-on adapter line out goes to the relocated filter bracket/filter.
Line out of filter goes to cooler w/thermostat and return to spin on port.
Line out to turbo from a fitting (somewhere) and return drain into pan.
Now should the PRV system run best integrated with the relocate and / or cooler OR should it be isolated?
Where can I economize the # and amount of lines needed.
Could we get specs on what we need (i.e. Oil spin on adapter is a M20x1.5, Lines are all -10 or ?, etc..)
Can we have another discussion thread on these??
What brands do u or DONT u recommend from your experiences?
So, does a new one come packed in oil and needs to be cleaned before sending to u? How do u recommend for those of us without access to a parts washer?
Can a used pump be a liability? I have 2 used or I could buy a new.
Any update on this?
One simplification to "the system" I have been thinking of running on the race car is the recently available combo oil filter mounts with built-in pressure adjusters. The cost is about the same as the two separate units but for space savings it might be worth looking at!!!

there are 15 pages and it would take a while to read it all so my questions are: is it completed? and how much is it going to cost?
Its been available since April.

You should update the first post in this thread with this info.
And please get back to me, I'll resend my PM.
