18 GT Whipple Gen 5 3.0l boost reference

[Ngetzem]

Hey guys looking for some confirmation before I wrap up the last couple items on my car. Over the winter I have torn into the car and one thing I did was install a lethal fuel system(duel regulator). Last thing I need to do after setting base fuel pressure is to connect my vacuum line to the regulator to boost reference from the Whipple. I’m thinking from the directions this is the line they want to T into.

Can anyone confirm this is the spot?

I think it’d be cleaner to put a fitting in the port on the back of the blower case under the MCT sensor. But, assuming that line goes to the bypass valve (looks like it does) then it will give you the same manifold pressure reference you are looking for.

The boost/vac port is located at the back of the blower. There's an NPT port plug there which you'll use to get boost/vacuum. The line coming off of the bypass valve at the front of the blower I believe is only vacuum which won't allow the regulator to raise fuel pressure from boost.

I used the open spot on front. Removed plug and added push lock fitting for hard line.
