I know this would sound a bit dumb to most, but here goes. I have an electric fuel pump gauge which I installed in with a 90. I can't come straight off the rail because my tank hits it when I lower it. I noticed my pressure fluctuated a bit so I went and picked up an earls 45 from Jegs. I noticed there is a very small amount of threads in the fuel rail before you would actually be impeding the fuel flow. Its only about the size of a pencil in there so is this normal or would I be causing an issue using this 45?
