    I'll guess it's vibration or over pressure of the pump??

    Poor design - the pounding of the hull bounces the body of the pressure regulator around. It is not restrained or supported by anything other than the short tubing to the metal nipple insert on the plastic pump hose fitting.

    The metal nipple is only held in place in the plastic hole by a tiny ridge on the metal insert. Any loosening of the grip that plastic has on the metal nipple, and out it comes with just a little force.

    Here is how I have been fixing them;
    How to repair a Ficht fuel injection fuel pump - pressure regulator has fallen inside

    How do you repair them, if you repair them?

    Lets go back 5 yrs Peoples
    Bernie: I am having fuel regulator issues .
    POLARIS: hUH
    Bernie :They keep falling out
    Polaris:What ?Weve never had that happen before Bernie .Your the only one, I have ever heard that has had this happen .Must be something your doing !!
    Bernie :All 5 of them ??
    Polaris :Hang on 1 other guy has had this issue and this is how he fixed it ,Now remove the pump push the regulator back in and drill a hole through it and retain it that way with a s/steel pin .
    Want to know why they aren't made any more .........

    They come loose because they swing like a pendilum inside as they aren't retained any way other than the piss weak excuse for a barb that is on the regulator and if the hose was 6"longer and retained against the pump it wouldn't work itself into the bottom of the fuel pump assy
    Shit design
