    Did it blow the media out or just split the side?
    Fleetguard had a bad run of filters about 6-7 years ago.

    Please share photos of the failure.

    HP Fuel pump and relief valve have nothing to do with the filter failure as the filter is on the low pressure side of the system.

    Sounds like a filter that should have failed quality control.

    I would have to look up exact specs. Only around 100-150 psi gear pump pressure.

    I have seen the large threads on the filter head get screwed up. Are you sure the filter is seating fully? It’s only blowing out the gasket?
