My friend is going to supercarge his v6 stang, he is going to just put in a boost gauge inside his car. I told him to put in a fuel pressure gauge also but, he wont listen to me he just wants to put one under the hood on the fuel rail and I told him to put it inside so incase his fuel pressure drops under boost. Do you have any good reasons so I can get him to put it inside his car.
because you need to monitor that stuff to keep from blowing the engine. His car, let him do what he wants
Put in an electronic one. They are real easy to install and monitor fuel pressure especially in a boosted car.
