    Mis-assembled cross over valve or a damaged/missing O-ring on the C valve. Only real possible causes. Do you have the assembly manual for your pump in order to check your work? If not you can get it here.

    the only thing i didnt do per instructions was to put very first o ring into pump.I put it on cage first and put second bigger o ring on shoulder loose like it says and then put it in the way they say.could that not seat the way its made to?It went on cage nice and tight like its made to do it!thought it would be easer to do it that way instead of trying to put o ring in pump first.The pump is still on truck when ive been working on it.

    The procedure you used of installing the O-rings on the cage is fine but it's easy to cut an O-ring while pressing the cage into place in the valve block., I know I've cut a few during installation. I'd recommend disassembling it again to recheck the O-rings on the cage assembly. I think you'll find one cut or damaged.
