CHANGING FUEL FILTER on the 6.7
 

I changed the fuel filter on my 2013 F-250, and my truck was running like chit:dang: Truck's was telling me :low fuel pressure: check engine light. Truck shut off on the highway while i was heading to work:argh: After work I went back & I took off & put back the primary fuel filter & the truck is running fine:jump: I must not have tighten the fuel filter housing when i changed the fuel filter the first time.:humm:

I had mine changed on my 99 F350, they put an aftermarket filter and cap on, shorted out the fuel heater and shut the truck down. Is yours an aftermarket filter? (I changed the filter with a Ford filter, new fuse, and it worked fine after that)

I used MOTORCRAFT fuel-filters, the problem wasn't the fuel-filer, the problem was that i didn't tighten the fuel filter housing all the way
