Thread: Anyone remove the vacuum line from FPR to boost bypass solenoid?

Has anyone removed the vacuum line that tees from the fuel pressure regulator over to the boost bypass electronic solenoid? Just wondering if the fuel pressure regulator still functions the exact same with and without the vacuum line (I'd cap off that side of the T)

been doing some vacuum line "remodeling" lately...

you need that.

you could run a line from the fpr to under the snout, then loop the by pass vac line around the back under the tb and tie it back in by the map sensor.

Wondering why it is needed though?? That line is only used when the solenoid is commanding boost bleed using the BBV right?

idk. but its there for a reason, id leave one in place. it wont matter how long the line is. as long as you have one.

Can say, I do like the idea of routing behind the blower just Teeing off of the MAP sensor line

maybe find a few wire tuck threads and see if you can see where they hid it in their pics.
