"The stock position of the fuel filter on my 2001 6. 6 Duramax was terrible. the filter was crowded against the engine a made it very difficult to change the filter. With the XDP Fuel Head Spacer Kit 01-16 6. 6L Duramax, it is much easier to get a filter wrench on the filter and reduces the possibility of getting the wiring harness damaged by a filter wrench,"
