Pan-E-Vac Question... What is the proper way to set up a pan-e-vac system? How should the tube going into the exhaust be shaped? What angle should it be at?
I don't want people the just quote what they've read. I want some solid proven info...

I have never pieced a set together but have used Moroso PN#25900. The kit comes with all the necessary parts. The 2 nipples are installed on a 45degree angle, 1/2 inch inside, in each header collector (midway in the collector)before the y-pipe/x-pipe. The important part is to have each nipple FACING the front so that the exiting gas has an easier job of pulling vacuum. The nipples are pre-cut on a 45 degree angle and installed in the header at 45degrees.
After the nipples you then thread on the 1 way check valve and from there go to the parts store and get some 5/8 heater hose( i always used the red color hose) to connect to the breathers that are installed in each valve cover.
This setup works good for a drag car but as soon as you put mufflers on it sort of stops working, way to much backpressure for a street car. I would put some anti sieze on the 1 way check valves to make it easier when taking apart. Hope this helps.

When you say to have each nipple facing the front what exactly do you mean? I think I kind of grasp what you are saying but i'm not sure..............
