Did you keep the white air-bleed in place on installation or install a new one?

still hissing everything is put back together right ,no fuel is coming out anywhere and still hissing any other suggestions? This is the key on not started

If it is correctly installed and there is no crack or loose fittings, you should not hear much. However, it may possibly be turbulence across the relief orifice, if it is not seated completely. What is your fuel pressure now both KOEO and running idle and WOT?

I dont have a fuel pressure gauge right now, i know i know , i need to get one asap and i didn't want to run the truck with the hissing, I am using the old o ring and fuel filter just to test it and they both are good, everything seems to be seated correctly, I just cant pin point where the exact hissing is coming from i know its form that area though, anything i can try doing? thanks for the help

Now the hissing sounds like its coming from inside the housing
