Hi,
I have to ask this question, not to make a bullshit adjustment on the fuel pressure.
According to my software spec. the fuel pressure shall be 3bar with vacuum pipe on
and 3,5bar with pipe off. The manifold pressure when the throttle is closed is appr. -0,7 to -0,8 and not -0,5bar.
So shall i adjust the pressure with vacuum pipe off or on?

 

Hi Mathias

Quoting Stu's fitting instructions:

3,5bar,with the small pipe removed and plugged,and around 3bar with it all connected as normal

So my guess it's best to set it with vacuum pipe off,but better ask Stu directly

 

They will normally rise to around 3.6-3.8 with the vac off, when set to 3 bar with it on, the vac OFF setting is the one to get right as this will be under load, so is more crucial than off load.

Thank´s for the info!
