EV boost gauge question

[Joshbaker]

Ok so I picked up an EV boost gauge from a guy pretty cheep. It is only the gauge. What all do I need to install it? It's the mechanical kind. Can I just pick up one of them plastic like kits from somewhere like autozone?

Depends if you have fittings with the kit or match fittings and the hose to the gauge. I'm assuming its 1/8" line.
