Default does anyone have one of these laying around?

VBP-VAC
For trans’s with vacuum modulator and Supercharger or Turbo
Vacuum/Boost Bypass Kit: All trans with vacuum modulator and supercharger or Turbo. Prevents boost pressure from causing runaway line pressure.

OR is there something else that does the exact same thing that I can use?

thanks!

WOULD AN INLINE CHECK VALVE WORK??


EDIT... NEVERMIND... JUST THOUGHT ABOUT IT AND IT WOULD HOLD THE VACCUM AND NOT CHANGE..

I usually have a couple in stock. Keep in mind that if you are running 10psi or more, that installing 2 of these are a good idea. Give us a call if you still need one.

Sorry to dig this up. Why would you need two if running more than 10 psi? Isn't the point of it not to push more than 10 psi through the line anyway?

We had found that in higher boosted combo's that some times we would see boost at the modulator. The second valve really is a safety for the other. HTH Vince
