Get one from a junkers or just install something similar to a blow off valve but reverse and splice it into the line so the booster will suck air in from that when it hits a certain pressure. I would just snag one from a junkers because the booster should be dissipating the extra vacuum on its own and it isnít. Worst comes to worst and you wanna be cheap about it, put a small hole in the line and make it bigger and bigger until the pressure is just right.
My jeep has only ever killed 3 things, a cat, a deer, and my wallet. What's the problem officer?
1992 Red YJ. Lifted, locked, and loaded with beer (Disclaimer: This doesn't mean said driver endorses drinking and driving, please enjoy alcohol responsibly and do not operate any vehicle of any kind, thank you....)
Thanks to the price of gas here ($4.25 a gal) I just bought a mountain bike, 0" of lift, 0" of travel, MT's, locked rear axle, oh yeah, it's the sh#$.
