FPR vacuum line, oops

[S13FX]

Ok so I was cleaning up my engine bay today after a exploded Radiator incident heh. And I got to my fuel rail. then I get to my FPR and lo and behold the vacume line to my FPR is disconnected. Im wondering what could be the effects of having a disconnected vacume line to the FPR?

Thank you

your cars fuel pressure would be running full pressure. so its extra rich from idle to cruising but wot open throttle wouud be the same.

your car should idle like crap too from a vacuum leak.

and would that also cause a slight hesitation at lower rpm ranges right after I shift?

[steve s14]

it definately can, due to it running on higher than normal fuel pressure and lower rpms.

You will be running rich under vacuum and running lean under boost. You'd also have a boost leak.
