| The reason why I'm searching for a vacuum leak even though I do not have a vacuum leak is because of low vacuum pressure. The vacuum pressure ranges from -430mmhg (17inhg) to -480mmhg (18.89inhg). This shows that the vacuum pressure is lower than what it should be. So, what I'm trying to figure out is WHY it's low. I am coming to the conclusion the fuel rail adapters are leaking, which I stated earlier. This would also coincide with the fact it takes a little bit longer to crank than previously. What I'm trying to figure out is will a leaking fuel adapter cause low vacuum.
