I ve seen a thread before but couldnt find it again sorry for a repost but i have an electric Fp guage and i get a lot of fluctuation(Sp). I was wondering how long i should run the filter before the Fass pump before i replace it and where to get a replacement. When i hit my brakes my fuel pressure rises. What does this and how can i fix it?

I would like to know the answer to this also I have had my FASS for about a year now and the fuel pressure rises when hitting the brakes. it has always done it. never could figure out why.

you need to put something in the the line to the gauge to snub or baffle the pressure hitting the gauge, such as a needle valve and just open it a couple turns
