bently says check valve is built in the pump but megaparts.com sells one for cis pump?anyone know? 200 82

i think my check valve is gone in my fuel system. the bently manual says that on the cis it is built in the pump and cant be replaced by itself. megaparts.com sells a check valve for this pump seperate for about 16.00. i am confused,i really hope i can replace just the check valve.

any sound coming from the main pump bad? i have a odd sound coming from the main pump that is not a whining sound like when you remove the intank fuse, also my intank pump always has a deep sound like luke skywalker's sword made when he moved it around.

    The check valve on Bosch single-stage fuel pumps used on Volvos up to 94 has the check valve as the outlet fitting onto which the fuel attaches.

    The in-tank pumps do not have a serviceable check valve (late in-tank pumps do not have a check valve).
