I recently picked up a G&R fuel filter relocation kit and engine filter delete. Running the Cat filter and water separator with the drain. It’s for a 2018 and correct me if I’m wrong but I have two WIF sensors, one on the engine mounted filter and one on the rear bed filter. I know I can get a WIF cooler for the engine mounted sensor but do I need one for the rear? If so, where can I get one?
