Has anyone run dual boost reference adapters stacked with a longer bolt?
I need another 3/16 vacuum port.
Here is a pic of my single, would it hurt the map sensor to be out twice as far?

The only double stack I can for sure say is good is at Wendy’s

I alread have a sensor threaded into the one, I need to mount another thread in sensor.

Use a threaded fitting into the adaptor. Attach a hose and run it to a threaded tee and attach both sensors.

Is there enough room to drill and tap another hole? Sorry not familiar with those so don't know myself off hand.

Next suggestion would be as above. Add threaded barb to vacuum line with a T.

Last would be doubling up. It "should" be fine but I'd be a bit concerned with a vacuum leak with heavy engine movement. Maybe TBA will custom make one for you too. Map should be fine as long as no leaks are created either way though.

Thanks for the input guys

I am going to give it a try.
The 6mm×1.0 bolt will need to be 2 3/4" long to run a double.
I will post up a pic once I install it.
