1997 Powder Special 580 EFI question please

[stingray719]

I bought a 1997 Powder SPecial 580 EFI that was not all together. My question is, there is a vacumn line from the pressure regulator on the fuel log (just like older GM cars) that is not connected. Can some one please tell me where it went originally?

Thanks!

Bill

I just looked at my friends sled (same sled as yours) that I'm doing motor work on........that vacuum port is open, it goes to ambient.

Thanks for the response. Seems odd though because in auto applications that pressure regulator helps control amount of fuel given to injectors. Unhook it on your early GM car and see the diff.

Anyways, Thanks!

Yes, nothing hooks up to that port on the regulator.
