Review on 🚗 Enhance Fuel Efficiency with the Motorcraft FD 4617 Fuel Filter by Mat Thompson

OEM filter for my 2008 6.4L. Arrived well packaged with o-rings and documentation. The network is full of videos on how to change them. The secondary in the engine compartment literally lasts a maximum of 5 minutes. The primary one under the driver's side railing takes a little longer as it's under the car. You will need to insert a plastic clip to keep the wire out so you have enough clearance. I would also recommend using an extension on your ratchet to give you a little more room. Without an extension, it's slow. I haven't figured out how to reduce the amount of detarget flowing out. Even after 30 seconds of draining, a decent amount (0.25 gallons) comes out when removed. It helps to have two decent buckets to collect as much as possible. I also turn the key 6 times for 30 seconds to start the fuel pump after each filter change. Takes a little longer as you have to do it twice but never had a problem. Plus the price was great.
