NPP Standalone vacuum

Wondering if anyone has come across doing a stand alone vacuum for the NPP rather than taping into the car system. I am just afraid that by breaking the tiny cap behind the engine bay near where the brak hose is connected, I may run into more problems later...

Ideas?

And even if you had an LS3, that's where the factory system hooks up to, that's why it's there.

That's not quite correct, those instructions are for that particular vendor, there are other vendors that use the factory setup, see the attached link. I have an LS2 and my NPP vacuum is tapped at the back of the manifold just like a factory LS3 system. It's in the instructions for my kit from Sunset Orange Creations who prefers the factory hookup. Look at post #7 & #18 in the attached link. These directions are for both an LS2 or LS3.

I preferred the factory setup and the system works perfectly.

To answer the OP's question, I believe it was the Mild to Wild system that originally had a kit with a vacuum pump that was installed in one of the rear storage wells to provide the necessary vacuum. I don't think that kit is still available.

I have a different solution - don't install the vacuum line at all and leave the butterflies open all the time!

(anyone wanna buy an unused Sunset NPP In-A-Box?)

That is certainly another option. However, being able to close them is called "co-pilot" option and sure comes in handy when needed. I have to admit, when going on long cruises on major highways, the drone can get a little tiring so it is nice to be able close the valves.

For all other driving, leaving them open is great.
