Why dual dumplines?
The cheat would be to install the tee in one of the two, one of the outs to a smaller dump, the other to another tee to each header.
You will have to play with the orifice size of the smaller dump to adjust the header cut in time.
Well I originally wasn't going to run a wet headers then after seeing and hearing how hot and loud they are I figured i would get popped for exceeding Db levels.
I also didn't want to run a pressure regulator and just wanted to have always the correct pressure for block. Talked to Greg at G&S he suggested two 8s in and 2 8s out would be fine that's what i stuck with.
I guess I could pull thermo housing and drill and tap a 3rd fitting ? Or just make a new one that has multiple ports.
Yeah now that I've ran new line to the dumps inquests I could cut one down low and add a tee to feed valve.
This is all new to me so it's a learning curve.
