Why no Fuel filter? - Ford F150 Forum - Community of Ford Jun 01, 20122009 - 2014 Ford F150 - Why no Fuel filter? - I have a 2011 5.0. It is coming up to about 30K miles now and I am planning to do the first major maintenance. Noticed there was no fuel filter in the truck, can anyone tell me why is that? Also any suggestions on what need to be done on the 5.0 for 30k? Spark Plugs? PCV.. 2015-2019 F-150 Air, Oil, & Fuel Filters | AmericanTrucks Engine filters keeps everything running smoothing.
