Hey so i finally go my fuel pressure guage situation figured out,and now i need to test it. I think that the fuel press is supposed to be around 36-38psi with the vac off right? now what exactly does that mean? do i pull the vac line out of the regulator or is it another vac line? i dont have a AFPR, mods in sig, and any help or info on the best way to test this would be awesome! thanks

Yup, the vac off means the vaccume line to the regulator is removed. I have mine set to about 37 psi. However, the AFPR is a tuning tool, so maby you should experement with different settings.

Awesome thats what i thought....now when i test it there isnt going to be a load on the engine, so if the pressure is any lower than 35ish then i might have some problems. Also how would i test it with a load on the engine? the guage is under the hood which makes it a PITA to look at it while driving! haha. thanks for the help guys!
