No problem installing the adapter and new Caterpiller fuel filter. My Duramax BZ diesel engine will now have cleaner fuel. Thank you for being a Market Leader.

First off the CAT filter looks sick hanging off the engine. The added insurance of the 2 micron rating plus the fact that the Cat filter has better flow and is way cheaper make this a no brainer. XDP got it to me fast and they have the best price!
Great Product!
