Genuine Bosch High Pressure Fuel Function Block, 2001-2004 GM 6.6L LB7

This is a Genuine Bosch function block. The valve in this function/distribution block could fail under load, causing low fuel pressure in the fuel rail and possibly putting the truck into limp mode. When this happens it could throw a P0093 code.

This includes the rail pressure sensor & pressure relief valve.
