    RRFPR pressure not bleeding off

    I have a custom rrfpr on my conversion. For some reason when i shut the ski off it holds pressure still from when it was running. Anyone have an idea why this might be happening or what I may have missed?

    When you pull the lanyard it should drop the pressure because the pump stop pumping and I believe the pressure bleeds off on the pump side of the reg not the return side like when bleeding eccess pressure. Maybe there is a piece of teflon tape in the reg or line that not letting it bleed back.

    Thats possible. When i first put the lanyard on and the fuel pump kicks in it goes up to 61base pressure. After a couple seconds it drops down a little bit. When I completely remove it then it drops to about 45psi then VERY slowly goes down in pressure

    While i think of it when do i set the base pressure, when the fuel pump first kicks in or after the pressure spike settles and goes down a little bit?

    My reg takes a little time to come right back down. Set the reg right when you put the key on but the important bit is to make sure you have enough pressure at full throttle not to be lean the base pressure will be what it is to supply the fuel uptop. R88

    putting in key will show you the base pressure, once you remove key, it should drop to 0 in seconds from what i have seen...

    OK,
    I'm going to check to see if any blockage or something on the reg. I'm running Xcharger and rxpx i/c with 42s and rrfpr. I'm looking for about 72 WOT pressure right?
    thanks guys

    AFR is what u want to look for, you cant go by a set fuel pressure, each ski will be diff unfortunately.
