Will this device allow the use of an 04.5-10 fuel filter housing on an 01 duramax?
View Staff Answer 

The XD138 Fuel Filter Head Spacer Kit is designed to allow the filter head to be spaced away from the engine. This makes it easier to get a wrench around the fuel filter. We didn't design this product for use with swapping an earlier model filter head so we have not tested it for that and cannot confirm that application.
