Hey everyone I currently have a boost gauge that I draw from the Manifold. I'm setting up water injection and have a pressure switch that needs boost pressure. I need another source, any ideas? I'm sure this is simple but its hard to search for this. Thanks.

 

You could always T into the MAP sensor line.

 

I have no clue where the map sensor line is, any pics or links?

 

David,

You can also run a T off of the manifold nipple line.

The map sensor is the small black box just above the master cylinder. There is a single vacuum line running to it from the UIM. My Defi boost gauge is T-d off from there.

 

I was gonna call you and ask, lol.

If I run a T off that line, both gauges get full pressure? Im a bit confused

 

Hehe, yep, both gauges get full pressure, or at least close enough that it doesn't matter.

 

thanks alot, I got a T i'll do it tomorrow.
