I'm gona do the vacuum hose job to solve my boost problem.

anyway should I reaplace hose for PCV and Purge control system?

I'm asking because this silicone hose is not good for fuel and oil
but those two line suppose to have a little gas vapor and oil should I worry and leave the factory hoses or just change them?

thanks..

 

I just did the hoses on mine and left the purge cont line stock but am going to elmininate the PCV line. If you check out the vac diagram for the 94-95 they dont have this line I believe.
