Hi, I swapped the feed line to -6an from the tank to filter and the stock feed for return, already I have the filter to rail -6an kit.

My fuel pressure at idle was 55psi, after the swap the pressure drop to 40psi. I fixed the pressure with the regulator (AEM 25-300BK). After let the car warm up checking for leaks and watching the pressure gauge I noticed randomly the needle flickering and becomes steady again.

Any help, Thanks.

The reason the pressure drop is because of the bigger return line, because technically the stock feed is about the same as 6an. also putting in a smaller orifice in the regulator will raise the pressure.
