I noticed that you asked Bob Putnam what he recommended and he said to run it down the left side of the intake....then you guys are all going off in strange directions with all kinds of extra length hose!
Bob is right -as usual.
I ran mine as he suggested - it does not cross over or near any exhaust pipes, it is short, and it doesn't look strange.....
Use -3 braided line - it is a sixteenth of an inch smaller than -4 and will result in quicker readings to the guage.
This is not that hard.
