i added a couple of psi of fuel yesterday when i noticed that when i put the line back on it only drops about 2spi. ive read it should be half of what your vacumm gauge is reading if thats so i was at 14hg which would mean i should be at 35-36 line on but im more around 39-40. could it be the gauge,regutaor or is it something else..i also checked for vacuum leaks and didnt find any
