Universal Vacuum Block and Boost Source Kit 3XXSS-001 By Procharger

You’ve got boost. You’ve got gauges. You’ve got parts that need to know what the heck is going on inside your intake manifold. That’s where this ProCharger Boost/Vacuum Reference Block steps in like the responsible adult at a party full of sensors.

Designed to work with most centrifugal supercharger setups, this block taps into the brake booster line—aka the straightest shot from the back of the intake manifold to that sweet, sweet boost and vacuum signal. Whether you’re running a blow-off valve, a Boost-a-Pump, or just want your boost gauge to stop guessing, this handy little block is the go-to solution.

It’s the same piece ProCharger includes in their HEMI supercharger kits, which means it’s battle-tested and trusted by folks who like going fast and having their engine parts communicate properly.

Installation is easy. No need to become a vacuum line philosopher or rig something out of old fittings and zip ties. Just pop it in and boom—instant pressure reference for whatever boost-hungry gadget you’ve got hooked up.

So, if your setup needs a vacuum/boost signal and you’re tired of sketchy T-fittings and questionable routing, this block is your clean, solid, “I actually know what I’m doing” option.

Pro tip: Your engine will appreciate not being treated like a spaghetti factory. Clean lines. Happy sensors. Go fast.
