3in Boost Leak Tester

Here is my 3D printable Boost Leak Tester that I made to work with my Takeda Turbo Inlet hose on my Veloster N. The main body measures 3in in diameter.

I couldn’t find anything off the shelf at the hardware store that was the right size so I 3D printed one and because I could, I made it fancy with the N logo.
I used this model to find a leak on the hose after the intercooler to the throttle body on my 2021 Hyundai Veloster N. A quick adjustment and tightening of the clamp and leak fixed!

You will need a pressure gauge. It will simply hand thread into the main body. This is the one I used:

You also will need a tire air valve. The hole for is 5/16" and the valve is held in place with a rubber seal and nut on the back side. This is the one I used:
