I remember hearing or been told that this line that branches off of the vacuum line tree should be as short as possible....

is this true?, mine's rather long and dangles all over....

if i didnt explain it properly, it's the pressure sensor on the left side of the engine bay if your looking at the engine with the hood up....

 

Yeah, I dunno man. Mine pretty much goes everywhere too. I figure the most important lines are the FPR and the pressure-sensor, so I have those be the "straight-shot" ones. However, the boost gauge and BOV lines are both tapped into that vac. source as well.

Just make 'em as short and straight-forward as possible. Just commonsense I guess.
