Default Latest boost leak

I switched back to the stock intercooler and have been chasing a few leaks.
I found all of them but one, but found it today after pressurizing the system.
I have a split in my plastic pipe the map sensor fits in. It only leaks after it pressurizes pretty good. It's split close to the hose by the firewall.
I couldn't make it leak with the low pressure pump on my smoker setup.
Anyone got an extra they want to sell?

As a temporary repair I took the pipe off, cleaned it squeaky clean, then used a couple rounds of guerilla duct tape and put 2 layers of heat shrink tubing over that. It is holding for now. Going to try to find a good used one and keep my fingers crossed in the mean time. I have a stage 2 malone tune.
