Everything You Want to Know About the Blue Clips! Changing Fuel Filter
The pressure will bleed off naturally over a few hours if the engine is not run in that time. Make it the first thing you do on a morning after the truck has sat all night. All I ever get is dribbles whenever I do it this way.
before you try to disconnect the fuel lines at the filter, you have to relief the fuel pressure. to do this, remove the splash shield which is on the left frame rail right under the drivers door. disconnect the fuel pump electrical connector, start the engine and let it idle until it stalls. after it stalls crank engine again for about 5 seconds just to make sure all fuel pressure is released. then your good to go. no more buckets of gas. install filter, plug in electrical connector and start engine.
Fuel filter help!!!!!!
Hi I can't get my fuel filter off my 2006 f150 xlt. I got the one hose off that goes to the gas tank but the other side I can't take off. It's different from the others. It's being held by a stainless steel bolt looking thing. I need help ASAP
Thank you
Thank you
Yeah same as above, read this and many other threads and watched vids to ensure I'm doing it right but it won't budge!
I think its going to get cut off and replaced with jubilee clips.
Oh and I'm not a complete novice either I'm a diesel engineer of 8 years. I have to say I've never seen such an over engineered piece of fuel line!

I found a solution to the fuel pressure relief and a method to empty the lines here:
I followed his suggestions and was very pleased with the results. I had no residual pressure on the lines and very little fuel leaked out when I removed the filter.

This picture is all that came out of the filter. (Bucket was dirty before I started)
In short, you take the cover off of the fuse box and remove the fuel pump fuse or the fuel pump relay, then run the engine until stalls and will not restart. The fuel line pressure has now been relieved and very little fuel will remain in the line.
When the filter is reinstalled, replace the fuse or relay and turn the key to the on postion 3 times, leaving the key in the on position for a few seconds each time to fill the lines. Then start the engine and check for leaks.
You will get fault codes that will clear in time or need to be cleared manually from running the lines empty.

Well this was very helpful when I replaced the fuel filter on the wife's 2005 Expedition today. Holy Cow was this overdue. The fuel ran out the back side of the fuel filter and looked rusty and nasty. The fuel that came out the front side did look cleaner but the fuel that came out of the line leading up to the engine had that same rusty look to it. I can hear a difference when the truck just idles now. Thanks for the tips and for the help. I only had to go to the parts house to get that set of quick release fitting tools.
My truck now has almost 99K miles on it. I usually change my fuel filter every 15-20K miles.
While laying under my truck changing it this morning, for some reason I thought about this how-to post. This is the post I found when I Googled "Ford F150 Fuel Filter Blue Clip/Connection" over 4 years ago when I changed my fuel filter on my 07 the very first time.
I have had other F150s but not with a connection like this, and I didn't want to break it.
I can say this post helped me out in crunch time and hope it has helped others.
