I've been running the dual Cat filter on my 12 CTD for 3+ years. It's amazing how clean the OEM fuel filter is after 10,000 miles.
That’s because it’s now not needed, assuming you have the after market filters up stream of the OE filter. You’re basically just causing more resistance on the low pressure side with no other benefits.
