    I'm having an issue with the Barrel valve breaking off at the mount point. This is the second time.
    Enderle K style valve bolted to a Hilborn Shotgun hat.
    The first time I had had some tire shake and chalked it up to that. I bought another housing and transferred the internals to it.
    Made a couple of shake free runs and bam! another breaks on the burnout.
    I'm at a loss as to what is causing this.
    Car is real soft on the launch at 1.05 best ET is 6.60 207
    I run a soft line to both the hat and port distribution blocks. I have seen both soft lines as well as hard lines being used.
    I have talked to others with the same setup and no problems.

    Any ideas please?

    Is the line from the pump in tension?

    Maybe posting a picture of the barrel valve mounted and where it's broken would help

    Make sure your pedal stop hits first-if not it can rip the valve off the injector

    Reviving an old thread.
    I have no idea hy two of these K style broke.
    I have changed to a cube and it is holding up so far.
    Thanks for all of the response
