edit: actually if you removed the thicker red line from your New Surge Tank, that's what I have.
My understanding with the level of the tank and lines is that the larger lines (about 3/4") are below the full line of both systems.
The smaller lines (about 3/8") are for when the system gets up to temp or hotter and fluid needs to "bleed out". When this happens the fluid begins to circulate through the reservoir.
So if I keep the new surge tank/reservoir at the same level as the OEM tank with the larger line going in on the bottom like the OEM and the smaller line in the top, it should function the same.
I'll have to wait and see. Maybe I'll try the tank on a stand outside the bay first for testing to see what level does what before mounting it.
Thanks for all the input.
