I was going to use this gauge but it is too small for where I want to use it.
Model is 150-121D
There is a red and green bulb colour to change the backlighting colour.
Never installed. Bought brand new from Mopac. Have receipt so you can take it back and exchange it for something else if you want.
$50
I also have the boost gauge tubing kit from 42 Draft Designs.
$25
