The pressure line from the dry sump pump goes into a remote mount oil filter. I bought a billet aluminum filter mount from Moroso and built a custom bracket that bolts on using the same bolts that hold on the hood hinge... this worked good... the mount is very solid and I didn't have to drill holes in the firewall or inner fender.
The pressure line exits the oil filter and is plumbed into a port at the back of the block.
I ran a tee of the main line line with a 3AN fitting and hose to my oil pressure gauge inside the car.

That's it for the dry sump plumbing
I would say that installing the dry sump system was much more work than I expected. It took several weeks after I installed the engine to mount the oil tank in the trunk and complete all the plumbing.
I decided to go with the dry sump so I could track the car and know that my engine would always have a good oil supply while cornering. The dry sump system should help to extend the life of the engine.
I know lots of guys on here run dry sump systems on their engines. I have not seen too much info on dry sump systems with the tank installed in the trunk. So far this has worked out good. The engine builder had lots of experience with this type of set up and said it would be no problem at all as long as all of the lines and tank are sized properly.
Glad I'm done with this part of the project...
