I’m wanting to put a fuel pressure gauge on my rxdi so I can monitor fuel pressure. I had an extra fuel rail laying around so I was looking at it and found a little plastic plug right below where the feed lines good in. I tapped it 1/8npt and was going to put a 90 degree fitting in it the put a fuel pressure gauge on it. My question is, is that a good spot to pick up accurate fuel pressure? I figured the rail would be just as good if not better spot then in line of the fuel line some where.
