DONT RECKING IM YELLING WHY WOULD SOMEONE WANT A BOOST GAUGE ON A CAR WITHOUT BOOST I WOULD JUST LIKE TO KNOW IF THERE IS ANY WAY TO CHECK THE GAUGE I PUT A VACCUM PUMP ON IT AND IT DIDNT WORK JUST WONDERING IF YALL HAD ANY IDEALS I APPOLIGIZE TO ALL THE FOLKS THAT THINKS I WAS YELLING I WASNT JUST MAKING A STATEMENT
well if the vacuum pump isn't making it move I would contact the person that made the boost gauge and see if you can get a new one under warranty if it's not too old.
