How much fuel pressure
#3
Here's what I found!
From viewing all the different GT Mustang forums, most people who own GT Mustangs report that their engines run best with their fuel pressure between 35 psi and 40 psi at idle. AllData has it between 35 psi and 70 psi as shown below. I assume they are talking about at idle and at wot. Good luck, Tommy.

So disconnect the vacuum and set it or adjust with vacuum on? Right now its reading about 32 with vacuum at idle and about 40 with vacuum wot. I have an adjustable BBk Regulator with a gauge built on it. If that helps anyone with info. Thanks
